Question

An atom has 2K and 8L electrons write down its electronic configuration and indicate
1) total number of subshelld
2) total number of orbitals

Answer 1

Answer:

8

Explanation:

The number of electrons in the shells is given as 2 in K shell, 8 in L shell and 5 in the M shell.

Thus, the atom has in total of 2+8+5 = 15 electrons.

Hence, the atom is phosphorus.

The electronic configuration will be as follows :

1s

2

2s

2

2p

6

3s

2

3p

3

Number of unpaired electrons = 3 (3p

x

3p

y

3p

z

)

The three unpaired electrons are in the 3p

x

, 3p

y

, 3p

z

orbitals respectively.

Hence, option (B) is correct.
