Question 1 Report

When an atom is in the ground state, it is said to be
Answer Details
When an atom is in the ground state, it means that all its electrons are in their lowest energy levels, which are also called their stable energy levels. In this state, the atom is said to be in its most stable and lowest energy state, and is less likely to undergo any chemical or nuclear reactions. When an atom absorbs energy, its electrons can move to higher energy levels, and the atom is then said to be in an excited state. Atoms in excited states are generally more reactive and can undergo chemical or nuclear reactions. Therefore, the correct answer to the question is "stable."
