Answer 1

A) Z = 12
$1s^{2}2s^{2}2p^{6}3s^{2}$

B) Z = 20
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}$

C) Z = 26
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{6}$

D) Z = 35
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}$

E) Z = 56
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{2}4d^{10}$$5s^{2}4d^{6}$

F) Z = 86
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{2}4d^{10}$$5p^{6}6s^{2}4f^{14}$$5d^{10}6p^{6}$

G) Z = 107
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{2}4d^{10}$$5p^{6}6s^{2}4f^{14}$$5d^{10}6p^{6}7s^{2}5f^{14}$$6d^{4}$

H) Z = 9
$1s^{2}2s^{2}2p^{5}$

I) Z = 10
$1s^{2}2s^{2}2p^{6}$

J) Z = 15
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$

L) Z = 28
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{8}$

M)  Z = 56
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{2}4d^{10}$$5s^{2}4d^{6}$

N) Z = 37
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{1}$

O) Z = 55
$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}$$5s^{2}4d^{10}$$5s^{2}4d^{5}$
