Answer 1

When an electron in a sodium atom gains enough energy to move from the second shell to the third the sodium atom becomes

an atom in excited state

Step-by-step explanation

• .The excited state occurs when valence electron absorb energy.
• The excited state takes the forms of electrons jumping from original energy level ( ground state) to empty orbital.
• When atom is in excited state it has a higher energy than in ground state
