Question

find the valency of N-7 and CL-17 in detail​

Answer 1

Answer:

Explanation:

For finding valency let's first write there electronic configuration

N = 2, 5

So valency = 8-5 = 3

Cl = 2, 8 , 7

So valency = 8-7 = 1

But as both will gain electrons in there outer most shell so

Valency of N = -3

Valency of Cl = -1

Answer 2

Answer:

Nitrogen's valency-3

Chlorine's valency-1

Explanation:

Electronic configuration of Nitrogen is 2,5

so it has to take 3 electrons or give 5 electrons to fulfil its octet or duplet respectively. As it is easier to take 3 electrons, that's why nitrogen's valency is 3

Chlorine has an electronic configuration of 2,8,7

it has to take 1 electron or give 7 electron to fulfil its octet

but it is easier to take 1 electron

so chlorine's valency is is 1
