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?
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
