Question

identify the following statements or words that makes \a\ correct an a. is the arrangement of electrons in the orbitals of an b. when all the c. in an atom have the lowest possible energies, the atom is said to be in its d. electrons electron configuration change atom energy levels ground state

Explanation:

• Electron configuration is the arrangement of electrons in orbitals.
• An atom is the basic unit where electrons are arranged.
• Energy levels are what have the lowest possible energies in the ground - state description.
• Ground state is when the atom's energy levels (electrons in a sense) have the lowest possible energies.

Answer:

A. electron configuration, B. atom, C. energy levels, D. ground state
