Question

which of the following phrases describes how the position of an electron relates to its energy? a. the farther an electron is from the nucleus, the greater its energy. b. the electrons within the core of the atom possess the highest energy. c. the farther an electron is from the nucleus, the lower its energy. d. the closer an electron is to the nucleus, the higher the energy level it is in.

Explanation:

Electrons in an atom occupy energy - levels. The energy of an electron is related to its distance from the nucleus. Electrons farther from the nucleus have higher energy as they are in higher energy - levels and are less tightly bound to the nucleus.

Answer:

A. The farther an electron is from the nucleus, the greater its energy.
