Question

Name two elements that you would expect to have chemical properties similar to Mg. What is
the basis for your choice?

Answer 1

Answer:

Ca - Calcium & Be- Beryllium

Explanation:

in Element Periodic Table ,

The columns, called groups, contain elements with similar chemical  properties  & behaviours .

Group which has Mg  called alkaline earth metal group

elements that would expect to have chemical properties similar to Mg are mentioned below.

Be  - Beryllium

Ca -  Calcium

Sr  -  Strontium

Ba - Barium

Ra  - Radium

as all the mentioned elements belongs to same column in periodic table Mg belongs and called alkaline earth metal group , hence all these have similar properties

Answer 2

Mg- atomic number - 12

electronic configuration = 1s² 2s² 2p⁶ 3s²

valence electrons = 2

valency = 2

As it belongs to 3 period and group 2

It belongs to alkali earth metals . hence the elements with above said properties fro the group 2 are :

• Beryllium
• calcium
