Answer 1

Answer:

just remember this sequence

1s 2s 2p 3s 3p 4s 4p 4d 4f 5s 5p 5d 6s 6p

remember

s orbitals can have maximum 2 electron

likewise p orbital can accommodate 6 electron

d orbital accommodate 10 electron

f orbital accommodate 14 electron

start filling the electron according to above sequence

there are lot of exception also so be careful

Answer 2

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 4 {d}^{10} 4 {p}^{6} 5 {s}^{2} 5 {d}^{10} 5 {p}^{6} 6 {s}^{2} 6 {f}^{14} 6 {d}^{10} 6 {p}^{6} 7 {s}^{2} 7 {f}^{14} 7 {d}^{10} 7 {p}^{6} 8 {s}^{2}$

Please scroll towards right✌️

please ignore the mistake and sorry if I'm wrong☹️

hope this helps u ❤️

keep smiling ☺️❤️
