Question

When an electron moves from a lower energy level to a higher energy level, the atom:

A. absorbs light
B. gives off light
C. becomes a new isotope

Answer 1

A. absorbs light

Step-by-step explanation:

For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.

In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.

When said electron comes back to the lower energy level, the atom will conversely give off light.
