Answer 1

Answer:

Bohr second postulate says that every orbit has a limit of electrons which it can hold

Answer 2

$\huge\colorbox{Limegreen}{Answer!}$

The allowed orbits in which electron can revolve are those in which the angular momentum of an electron is an integer multiple of h/2π, where h is planck's constant having value 6.63 * 10^-34 Js. I. e if m and v are the mass and velocity of the electron in a permitted orbit of radius r, then

mvr = nh/2π

Where n is called principal quantum number and has the integer values 1,2,3...
