List the quantum numbers for the electrons in the ground state of a neon atom. What are the quantum numbers for the next state to be filled in this scheme? If a single electron were excited by the minimum amount of energy possible, what would then be the configuration of the atom?

Solutions

Expert Solution

simple first the atomic no of Neon is " 10 "

electron configuration of the Neon is 1S2 2S2 2P6

now for 1 S2 : n = 0 , L = 0 , mL = 0 , s = 1/2 , ms = + 1/2

n = 0 , L = 0 , mL = 0 , s = 1/2 , ms = - 1/2

for 2 S2 : n = 1 , L = 0 , mL = 0 , s = 1/2 , ms = + 1/2

n = 1 , L = 0 , mL = 0 , s = 1/2 , ms = - 1/2

for 2 P6 : n = 1 , L = 1 , mL = - 1 , s = 1/2 , ms = 1/2

n = 1 , L = 1 , mL = 0 , s = 1/2 , ms = 1/2

n = 1 , L = 1 , mL = 1 , s = 1/2 , ms = 1/2
