Answer 1

EXPLAINATION :

1.)

Neil bohr postulates that the electron in a hydrogen atom can I occupy any of a series of circular path, known as Shells. Each of these is characterized by a fixed Energy level.

2.)

Option D is the correct answer.

Reason:

Li Li elec (9,1] (2,6) (2,11 config. + @100 Lizo

Lithium oxide, Li20 • Each lithium atom loses one electron to form 2 cations Lit (2 electrons in total are lost) Oxygen atom gains two electrons to form the 2- anion 02- • Lithium oxide compound can be represented as Li :09 Li

Hope, This helps you alot for your better understanding.
