Question

Q1.Write the Lewis dot method for beryllium and calcium ?​

Answer 1

Explanation:

Lewis dot structure for Beryllium:

Beryllium has atomic number 4.

So, it's electronic configuration is 1s² 2s²

So, as per shell :

$K_{2} L_{2}$

Now, refer to the 1st diagram.

Lewis dot structure for Calcium:

Calcium has atomic number 20.

So, it's electronic configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².

So, as per shell :

$K_{2}L_{8}M_{8}N_{2}$

Now, refer to 2nd diagram.

_________

In Lewis Dot Structure, we will simply denote the number of valence electrons decide the name of the element.
