Question

Calculate the energy of electron in 4th orbital in Bohr model

Answer 1

E = -13.6/n^2 eV

orr 2.18 * 10^(-18) / n^2 Joules

i will use first formula u can convert it in joules by either multiplying by 1.67 x 10^-19 (charge on electron)

so... E =- 13.6 / 16eV

= -0.85 eV

Answer 2

Explanation:

Electrons can only move from one orbital to another allowed orbital at one time. If an electron drops down from n=2 to n=1 energy is emitted, and if the electron moves up from n=1 to n=2 energy is absorbed. The amount of energy that is either absorbed or emitted is called quanta.
