Question

match the following
1) Nitrogen { } A. 1
2) magnesium { } B. 2
3) sodium { } c. 3
4) carbon { } d. 4​

Answer 1

Answer:

nitrogen - 3

magnesium - 2

silicon - 1

carbon - 4

Explanation:

1) nitrogen electronic configuration is (2,5) so it will give 3 electrons so it's valency will be 3.

2) Magnesium electronic configuration is (2,8,2) so it will give 2 electrons so it's valency will be 2.

3) sodium electronic configuration is (2,8,1) so it will give 1 electron so it's valency will be 1.

4) carbon electronic configuration is (2,4) so it will either give 4 electron or take 4 electron so it's valency will be 4.

Answer 2

Answer:

nitrogen -3

magnesium -2

sodium -1

carbon -4
