Answer 1

Just remember how many electrons can each sublevel hold.

S=2
P=6
D=10

Since we have 10 for atomic number, we can assume we have 10 electrons

1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)

Answer 2

Answer : The electronic configuration of Atomic number 10 is,
`1s^22s^22p^63s^03p^04s^03d^04p^05s^0`

Explanation :

Electronic configuration : It is defined as the arrangement of electrons of an atom in an atomic orbitals.

In the electronic configuration, the s, p, d, f are the sub-shells which can hold 2, 6, 10, 14 electrons respectively.

Given : Atomic number = 10

Atomic number = Number of electrons

The number of electrons = 10

The electronic configuration of Atomic number 10 is,
`1s^22s^22p^63s^03p^04s^03d^04p^05s^0`
