Question

If an atom has complete k and l shells what would be its atomic number

Answer 1

Answer:

Explanation:

electrons in k shell = 2

in l shell = 8

number of electrons = no of protons

atomic no = 2+8

                =10

thus it is Neon gas

Answer 2

Answer:

Electrons in K shell =2

Electrons in L shell =8

no. of electron =no. of protons

atomic no.=2+8

=10
