In general, is there a relationship between the locations of metals on the periodic table and their relative activity? The Elements located in the periods near the top of the periodic table tend to be more reactive, while the ones close to the metalloid boundary and on the bottom left have not as much reaction. 4.)
What are the majority of elements on the periodic table?
The majority of elements on the periodic table are metals. This periodic table groups elements according to type: metal (blue), nonmetal (yellow), or metalloid (red). All of the metals are grouped together on the left side of the periodic table. Notice that hydrogen, colored red, is grouped with the metals in the top left corner.
How are elements arranged on the periodic table?
In the modern periodic table, elements are arranged according to their atomic number. You can imagine a zig-zag line, starting at B-Al-Si, separating metals from non-metals. The periodic table shows that metals are found in groups 1, 2 and 3. These metals will have 1, 2 or 3 electrons in the outer shell.
How does the reactivity of metals vary down the group?
For group 1 and 2 metals, reactivity generally increases down the group. This is as metals form ionic substances when they react with a non-metal. In this, they lose their outer shell electrons in order to become a positive ion.
Why do metals and non-metals react differently?
These differences in reactivity depend on where an element is placed in the periodic table. Metals and non-metals are found in different parts of the periodic table. They have different electronic structure, and this influences the way in which they react.

Is there a relationship between the reactivity of a metal and its position on the periodic table?
The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
How does the position that the metals occupy in the periodic table correlate with their reactivity with HCl?
Hydrochloric acid (HCl) reacts readily with most metals other than those in the platinum group in the periodic table. Generally, the metals at the far left of the periodic table react most strongly, and as you progress towards the right side, reactivity lessens.
What can you conclude about the reactivity of metals as you move across a period?
Metal reactivity decreases from left to right across periods and increases down groups. nonmetallic characteristics increases from left to right and decreases down groups. Nonmetal reactivity increases from left to right and decreases down groups.
What is relative reactivity of metals?
The relative reactivity of a group of metals can be established by comparing the reaction of each metal with a given reagent. A metal might react with a specific reagent or no reaction may occur. On the other hand, a given metal might react with a specific reagent at a different rate than some other metal.
Does the reactivity of metal increase or decrease from bottom to top?
The reactivity of an element belonging to metals increase on moving from top to bottom in a group of the periodic table. While moving from top to bottom in a group of the periodic table, the reactivity of non- metals decreases.
Why does the reactivity of metals increase from left to right on the periodic table?
Why does the reactivity of metals increase from right to left on the periodic table? Metals on the right have fewer protons, making it harder to attract electrons from other atoms. Metals on the right have fewer valence energy levels, so electrons are closer to the nucleus and harder to pull away.
What happens to the reactivity of metals as you move across a period explain in terms of shielding and nuclear charge?
As you go across, the nuclear charge increases so there is a stronger attraction for electrons therefore it is harder to lose electrons so reactivity decreases. As you move down a group, reactivity increases.
Why does the reactivity of metals increase from right to left on the periodic table quizlet?
For metals, the reactivity decreases as we go from left to right across a period because the farther to the right of the periodic chart we go, the harder it is for electrons to be given or taken away, resulting in lower reactivity.
What happens to the reactivity of metals as you move down a group?
Metal reactivity increases down a group because as nuclear shielding increases and the nucleus' hold on the valence electron weakens, therefore it is easier to remove valence electrons.
How do you determine the reactivity of metals?
Count the number of bubbles produced in a given time. The bubbles are hydrogen gas and can be confirmed using a lit splint, which will produce a 'squeaky pop' when the hydrogen burns. The faster the bubbles are given off, the faster the rate of reaction and the more reactive the metal.
How do you determine the order of reactivity of metals?
The reactivity series In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions .
Why the metals at the bottom of the activity series is not taken part in chemical reaction?

Magnesium, mossy zinc and copper foil are reacted with hydrochloric acid to produce hydrogen gas and a salt.
What does HCl do in a reaction?
Hydrochloric acid and hydrogen chloride react violently with many metals, with the generation of highly flammable hydrogen gas, which may explode. Reaction with oxidizers such as permanganates, chlorates, chlorites, and hypochlorites may produce chlorine or bromine gas. National Research Council.
How does the periodic table order elements?
The periodic table describes the elements in their very atomic origin ordered by the number of protons in their nuclei (atomic number). The different neutron configurations that describe the isotopes per element are left out. Besides atomic number it orders elements according to electronic configuration to classify elements with similar chemical behavior. That can be in the form of columns or in the form of rows.
Where does reactivity of metals increase?
Generally, reactivity of metals increase going to the left of a period and down a group.
Why are Caesium and Francium reactive?
That is what makes group 1 so reactive: they will give their valence electron to anything nearby to achieve their goal. Reactivity of group 1 metals goes up as we go down the group, which is why we have Caesium and Francium as our most reactive metals. These two elements are also the biggest (atomic radius) of the group 1 me
What happens when you go down a group?
Going down a group, you have generally increased valence electron shielding, meaning the outer shell electron is less electrostatically attracted to the positive nucleus as there are more electrons between the two as you move down the group. This also influences the reactivity on the element, however this is also highly interconnected with whether the element is a metal or a non metal.
Why does electronegativity decrease?
The more willing an element is at giving away electrons, the less electronegative it is. Electronegativity generally decreases going to the left because the nuclear charge of the atom decreases and so does the nucleus' attraction for outer shell electrons. Electronegativity also decreases going down a group because the number of quantum shell increases so outer shell electrons are further aw
How does reactivity affect metals?
For group 1 and 2 metals, reactivity generally increases down the group. This is as metals form ionic substances when they react with a non-metal. In this, they lose their outer shell electrons in order to become a positive ion. As you go further down a group, the size of the whole atom increases as the outer shell electrons get further away from the nucleus as an extra main energy level is being added as you move down each consecutive period. As the electrons get further away, they ‘feel’ less of an attraction from the positive nucleus and so they are more easily lost to the non-metal. This i
Why is chlorine so reactive?
Chlorine is particularly reactive because it is only one electron away from fulfilling it's octet. When atomic chlorine is around lock up your daughters and keep one hand firmly on your wallet.

Do non-metals lose electrons?
For this reason, metals are more likely to lose electrons to form a full outer shell. Non-metals are mostly found in groups 5, 6 and 7. These non-metals will have 5, 6 or 7 electrons in the outer shell. The outer shell of a non-metal is, therefore, more than half full of electrons. For this reason, non-metals are more likely to gain electrons ...
