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.
excited state emits energy

Explanation:

Step1: Understand electron - energy relationship

When an atom gains energy, electrons move to higher - energy levels and enter an excited state.

Step2: Determine what happens after excited state

When electrons return to lower - energy levels from the excited state, they emit energy. So the first blank is "Ground state" (before gaining energy to reach excited state) and the second blank is "Returns to ground state" (after excited state before emitting energy).

Answer:

Ground state; Returns to ground state
