(d) 1s2 2s2 2p6 3s2 3p6 3d2 4s1 (e) 1s2 2s2 2p6 3s2 3p6 3d2 4s2The sub shell electronic configuration of an element is 1s2 2s2 2p6 3s2 3p3. On the

basis of this answer the questions below.

(a) Number of shells in the element.

(b) Name the sub shells in each shell

(c) Atomic Number

(d) Number of electrons​

Answer 1

Answer:

a)1s2 2s2 2p7

Explanation:

because p orbital can accommodate only 6 electrons .. that should be 2p6

Answer 2

Answer:

(I)1s2 2s2 2p7...(II)(a)2..(b)s,p...(c)15...(d)15

Explanation:

I hope it helps ☺️
