Question

section 4.3 modern atomic theory (pages 113 - 118)
this section focuses on the arrangement and behavior of electrons in atoms.
reading strategy (page 113)
sequencing after you read, complete the description in the flow - chart below. write how the gain or loss of energy affects electrons in atoms. for more information on this reading strategy, see the reading and study skills in the skills and reference handbook at the end of your textbook.

Explanation:

When an atom gains energy, its electrons move to higher - energy levels, resulting in an excited state. When the electrons return to their lower - energy levels (ground state), the atom emits energy.

Answer:

Gains energy; Returns to ground state
