Rubidium (Rb), Cesium (Cs), Francium (Fr), Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra).
Why are representative elements called so?
Representative elements are called representative elements because they are true to the general properties expected of the group they belong to; this is because the representative elements of a group exhibit similar electron configurations, with the same number of electrons in their valence shell.
Which among the following is representative element?
In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
Are noble gases representative elements?
The noble gases (group 18) do not come under representative elements as they have a fully filled configuration and they are unreactive in nature. The d block elements are called as transition elements as they have properties transiting from metals and non – metals.
Which columns are representative elements?
The first two columns on the left and the last six columns on the right are called the main group or representative elements. The ten-column block between these columns contains the transition metals. The two rows beneath the main body of the periodic table contain the inner transition metals.
What are representative elements?
The representative elements are those found in the first two groups of the periodic table and in groups 13 through 18. They are also referred to as the main-group elements and comprise all known elements, except the transition metals located in the center of the periodic table. Elements are organized in the periodic table according ...
How are elements organized in the periodic table?
Elements are organized in the periodic table according to their physical characteristics and chemical behaviors. The representative elements in group one are called the alkali metals, and they each possess only one valence electron in their outermost electron shell. The alkali metals are soft, lustrous metals that are highly conductive.
What are the nonmetals in group 18?
The nonmetals in group 18 are called the noble gases, and they mostly do not form bonds with other elements because their electron configurations are stable on their own, although there are exceptions. ADVERTISEMENT.
Which group of metals are harder than the alkali metals in group one?
Group two representative elements are called the alkaline earth metals. These elements are harder than the alkali metals in group one.
How many groups of elements are there in the representative elements?
The representative elements include eight groups, including the most abundant elements on the planet, not to mention the calcium for your bones, the potassium for your leg cramps, the iodine for Fluffy. . . well, you get the idea. Learning Outcomes. After you have finished this lesson you should be able to:
What is the periodic table?
The periodic table is a chart that groups elements together based on similar characteristics and atomic structures. The Periodic Table. You'll notice that the symbols are used to save room. For example, instead of aluminum, the periodic table says Al.
What element group has 6 valence electrons?
Let's check out group 6A, or the chalcogens. This group of elements varies greatly. For example, it contains oxygen, a colorless gas vital to your survival, as well as polonium a radioactive metal that can kill you. Although there is a lot of variation amongst elements in this group, they all have six valence electrons.
How many valence electrons does group 3A have?
Even though each group varies greatly, you can take comfort in knowing that group 3A has three valence electrons, group 4A has four valence electrons, and group 5A has five valence electrons.
How does the periodic table organize elements?
The periodic table organizes elements based on similar characteristics. Each group or family has the same number of valence electrons, which gives them similar properties, such as reactivity (even if they do look completely different).
Which group of gases has eight valence electrons?
Our tour will conclude with group 8A, or the noble gases. With the exception of helium (which has two), this group has eight valence electrons. This makes noble gases extremely stable, meaning they aren't likely to react with other elements.
Why do groups 1 and 2 have alkali?
Both group 1 and 2 have alkali in their name because they create a base (something with a pH greater than seven) when they react with water. Let's travel to the right of the periodic table and take a look at 3A, 4A, and 5A, none of which get fancy names. Some of the elements in this group are very abundant on Earth.

What are the groups of elements that are representative?
Representative elements are in the group1, group 2, and in groups 13 to 18. Transition elements are in the groups 3 to 12. Colours. Most of the compounds formed by representative elements are colourless. All the compounds formed by transition elements are colourful.
What are transition elements?
Transition elements are chemical elements that have unpaired d electrons at least in a stable cation that is can form. Representative elements include s block and p block elements.

What are the elements in the S block?
S block elements have their valence electrons in the outermost s orbitals and are in two types as alkali metals and alkaline earth metals along with hydrogen and helium. Alkali metals are group 1 elements (excluding hydrogen) whereas alkali earth metals are group 2 elements. These metals are named as such because they form basic or alkaline compounds. Alkali metals include Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Alkaline earth metals include Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
Which group of elements have unpaired d electrons?
Transition elements are chemical elements that have unpaired d electrons at least in a stable cation that is can form. All the transition elements are metals. They have their valence electrons in the outermost d orbitals. Therefore, all the chemical elements from group 3 to group 12 are transition metals excluding zinc ...
What are the two groups of elements in the periodic table?
There are periodic trends in the periodic table. All the elements in the periodic table can be divided into two groups as representative elements and transition elements. The key difference between representative elements and transition elements is that representative elements are the chemical elements in the group 1, ...
What is the difference between transition elements and representative elements?
The difference between representative elements and transition elements is that, representative elements are the chemical elements in the group 1, group 2 and in the groups from 13 to 18 whereas transition elements are chemical elements in group 3 to group 12 including Lanthanides and Actinides.
