Question

Bohr's theory is not applicable to
1) Li+2
3) He+
2) Lit
4) Both 1 and 3​

Answer 1

answer

Bohr's theory is applicable to hydrogen like atoms (single electron system). 

Here, Li2+ and H-atom consists of only one electron. He, He2+ consists of 2, 0 electrons, respectively.

Hence, options A & C are correct.

Answer 2

Bohr's theory is not applicable when an atom has only one electron in the outermost layer

so in these above questions Li has only one electron in its outermost shell so Bohr's theory is not applicable for it..
