Question

The last element of the p-block in 6th period is represented by the outermost electronic configuration.

• (i) 7s2 7p6

• (ii) 5f14 6d10 7s2 7p0

• (iii) 4f14 5d10 6s2 6p6

• (iv) 4f14 5d10 6s2 6p4

​

Answer 1

Answer:

Option:iii

Explanation:

Cause it should have 6 orbital and inert number of electrons

Answer 2

1period--1s2

2period--2s2 2p6

3period--3s2 3p6

4period--4s2 3d10 4p6

5period--5s2 4d10 5p6

6period--6s2 4f14 5d10 6p6

Hence the answer is iii
