What do all alkaline earth metals have in common?
The Alkaline Earth Metals
- Properties of Alkaline Earth Metals. The alkaline earth metals comprise the group 2 elements. ...
- Reactions of Alkaline Earth Metals. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge.

What are some interesting facts about alkaline earth metals?
What are 3 facts about alkali metals?
- Because they are so reactive with air and water, they are generally stored in oil.
- Cesium and rubidium are used to make atomic clocks.
- Sodium and potassium both play an important role in biological life on Earth.
- Sometimes cesium is also spelled “caesium.”
What are alkaline earth metals found in?
Magnesium and calcium are quite abundant in both the earth's crust and in sea water. Beryllium is significantly rarer in the crust than the other 4 non-radioactive metals. The reactivity of the alkaline earth metal increases as you move down the column.
What do alkaline earth metals make?
In chemical terms, all of the alkaline earth metals react with the halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds (except for beryllium chloride, which is covalent).
What are 2 interesting facts about alkaline earth metals?
Interesting Facts about Alkaline Earth Metals They are called alkaline because they form solutions with a pH greater than 7, making them bases or "alkaline." Radium is formed from the decay of uranium. It is very radioactive and is dangerous to handle. Calcium and magnesium are important for animal and plant life.
What is an example of an alkaline earth metal?
The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) are the second most reactive metals in the periodic table (Table 3.7), and, like the Group 1 metals, have increasing reactivity in the higher periods.
What are the 3 alkaline earth metals?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What are 5 properties of the alkaline earth metals?
Key PointsAlkaline earth metals have two valence electrons.They have low ionization energy, low electron affinity, and low electronegativity.They are highly reactive and often form divalent cations.They are good conductors of electricity.Alkaline earth metals have an oxidation state of +2.
Do alkaline earth metals form bases?
The second group elements called alkaline earth metals. Earth* because of the reason that their oxides found in earth crust as Be oxides are rare and found in earth crust, and alkaline* because their oxides are basic in nature and form basic solution in water.
Electronic Configuration
Physical Characteristics
- 1. Atomic and Ionic Radii – Due to the high nuclear charge of alkaline earth metals, the electrons are attracted strongly towards the nucleus. As a result, the atomic and ionic radii are smaller than those of the corresponding alkali metals; on moving down the group, atomic and ionic radii increase due to adding an extra shell of electrons in each succeeding element, increasing the sc…
Chemical Properties
- Alkaline earth metal is smaller in size when compared to the corresponding alkali metals. However, they have higher cohesive energy, higher ionization potential and higher enthalpy of sublimation as well. The reactivity of alkaline earth metals is high however, it is relatively less when compared to the reactivity of alkali metals. It will be quite apparent from the following disc…
Alkaline Earth Metal Uses
- Uses of Beryllium
1. Alloys of beryllium are quite helpful. For example, \({\rm{Cu – Be}}\) alloy uses in making high-strength springs. 2. The metal is used for making windows of \({\rm{X – }}\)ray tubes. 3. It is a source of neutrons when bombarded with alpha- particles. 4. Beryllium and its compounds find … - Uses of Magnesium
1. It is used as a reducing agent in the preparation of silicon and boron from their oxides. 2. Magnesium is used in the preparation of Grignard reagents, which are alkyl magnesium halides. These are organic compounds and used in the synthesis of a large number of compounds. 3. It …
Summary
- From what we discussed so far, it is clear that group II elements and their compounds show gradation in their physical and chemical properties. Hence, their inclusion in group II of the periodic table is justified. In this article, we studied the second group of metals- their occurrence, properties, and trends. We also learned the uses of various alkaline earth metals.
