Answer 2

$\mathscr{\huge{\green{\underline{\underline{Answer:}}}}}$

• Electrons move around the nucleus in circular orbits of fixed energy and size.
• An electron can jump between these orbits by absorbing or emitting energy.
• The energy difference between two states is given by, ◇E=E2-E1
• It explain the stability of atom and the line spectrum of hydrogen .
