1) The atom absorbs energy, and one or more electrons move to a higher electron shell.

An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption.
The electron absorbs the energy and jumps to a higher energy level.
In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

So all the statements except 1) are false.
