absorption

a state in which an atom has a higher potential energy than it has in its ground state.

energy must be added to an atom in order to move an electron from a lower energy level to a higher energy level.

the lowest energy state of an atom.

the process in which an electron falls to a lower energy level and a photon is emitted.

Explanation:

• Ground State: The lowest energy state of an atom. This is the most stable state for an atom as it has the least amount of potential energy.
• Excited State: A state in which an atom has a higher potential energy than it has in its ground state. Energy (usually in the form of photons) is absorbed to move electrons to higher - energy levels.
• Absorption: Energy must be added to an atom in order to move an electron from a lower energy level to a higher energy level. This is the process of absorption where the atom takes in energy.
• Emission: The process in which an electron falls to a lower energy level and a photon is emitted. When an electron relaxes from a higher - energy level to a lower one, the excess energy is released as a photon.

Answer:

• Ground State: The lowest energy state of an atom.
• Excited State: A state in which an atom has a higher potential energy than it has in its ground state.
• Absorption: Energy must be added to an atom in order to move an electron from a lower energy level to a higher energy level.
• Emission: The process in which an electron falls to a lower energy level and a photon is emitted.
