What is the state called when an atom's electrons are in their lowest energy configuration?

1. Deficiency

2. Ionization

3. Stability

4. Equilibrium

The correct answer is: Equilibrium

The state of an atom with its electrons in their lowest energy configuration is referred to as equilibrium. In this context, equilibrium indicates that the electrons occupy the most stable and energetically favorable arrangements, which minimizes the energy of the atom. In chemical terms, when electrons are at their lowest energy state, they are not in a position to lose or gain energy easily, contributing to the overall stability of the atom. Other terms like deficiency, ionization, and stability do not accurately describe this specific state. Deficiency refers to a lack or shortfall of something rather than an energy state of an atom. Ionization involves the process of an atom gaining or losing electrons and thus reaching a more energetic and reactive state rather than being in a low energy configuration. While stability is a broader concept that can imply low energy, it does not specifically denote the scenario of lowest energy configuration related to electron arrangement. Therefore, equilibrium is the most precise term to describe this state.
