Outcomes of Bohr’s Model :

Bohr's energy= -13.6×(z²÷n²) eV

Bohr’s Radius = 0.529×(n²÷z)

Velocity of an e- in nth state = 2.16×106×(z÷n) m/s

When an e- jumps from a lower level to a higher one, some energy is absorbed while some energy is emitted.

Thus, if an e- jumps from orbit 1 (energy E1) to orbit 2 (energy E2) the change is given by

E=E2-E1=hv

Each energy level is associated with a fixed amount of energy. The shell nearest to nucleus having minimum energy and shell farthest from nucleus having maximum energy.

Due to presense of equal no. of negative e-s and positive protons, the atom as a whole is electrically neutral.
