Which atom absorbs more energy- one in which an electron moves from the the second shell to the third shell, or an atom which an electron moves from the first to the third shell?

Respuesta :

An atom which an electron moves from the first to the third shell atom absorbs more energy.

An atoms may occupy different energy states . The energy states are discrete , that means they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.

The lowest possible energy levels that the atom can occupy is called ground state.The energy levels which is higher to the ground state is called excited state.

The more energy absorb when electron move from first to third because in this second energy level have to pass to reach at third energy level.
