Answer 2

Answer:

Phosphorus=2,8,5

Silicon=2,8,4

Explanation:

1) Phosphorus.

Since the atomic number of Phosphorus = 15

Therefore, it's electronic configuration will be

= 2,8,5

Here we can say that it's valency = 5

2) Silicon.

Since the atomic number of Silicon = 14

Therefore, it's electronic configuration will be

= 2,8,4.

Here we can say that it's valency = 4.
