Question

multiple choice question
the ground state of an atom is _.
o its lowest allowable energy state
o its highest allowable energy state
the difference between its highest and lowest energy states
the difference between its lowest and next lowest energy states

Explanation:

In atomic physics, the ground state of an atom is defined as the lowest energy state that the atom can occupy. When an atom is in its ground state, it has the minimum amount of energy possible. Higher - energy states are called excited states.

• The option "its highest allowable energy state" is incorrect because that would be an excited state.
• The options involving differences ("the difference between its highest and lowest energy states" and "the difference between its lowest and next lowest energy states") are incorrect as the ground state is a single - state description, not a difference.

Answer:

its lowest allowable energy state
