Why does calcium and magnesium belong to the same group?
These chemical elements are collectively called as the Alkaline Earth Metals. Beryllium, Calcium and Magnesium are three of the six elements that fall into this category. The outer electronic structure of all these elements is similar due to which they all have similarity in their chemical and physical properties.
What is the valency for magnesium and calcium?
Atomic Structure | Exercise
Elements/Radicals | Symbol | Valency |

4. Calcium | Ca | 2 |
5. Aluminium | Al | 3 |
6. Magnesium | Mg | 2 |
7. Zinc | Zn | 2 |
Is mg Ca and Ba have same valency?
Detailed Solution. The correct answer is Mg, Ca, Ba.
Do calcium and magnesium have the same number of valence electrons?
On the other hand, boron , and argon have 3 and 8 valence electrons respectively. Aluminum and calcium have 3 and 2 valence electrons respectively. And potassium and magnesium , have 1 and 2 such electrons.
Why are elements beryllium and magnesium in the same group?
All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. Covers the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba).
Which elements have similar properties to magnesium?

Why is the valency of magnesium 2?
Magnesium has valency equal to 2^+ because the electronic configuration of Mg is [2,8,2]. The nearest noble gas to magnesium is neon with electronic configuration of [2,8], to achieve this stable electronic configuration Mg can lose 2 valence electrons, hence its valency is 2^+ .
What is magnesium valency?
The electronic configuration of magnesium is 2,8,2. The valence shell contains 2 electrons. Therefore the valency is two.
Does calcium and magnesium have 2 valence electrons?
All alkaline Earth metals have similar properties because they all have two valence electrons. They readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.
What is valency of magnesium?
Are calcium and magnesium in the same period on the periodic table?
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). They are harder and less reactive than the alkali metals of Group 1A….Group 2A — The Alkaline Earth Metals.
