Ev as the Unit of Energy:
Ev (electron-volt) is a unit of energy. It is the amount of energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
1 electron-volt (Ev) is equal to 1.602 × 10-19 joules.
It is commonly used in atomic, nuclear, and particle physics to measure small amounts of energy.
When an electron moves across an electric potential difference of 1 volt, it gains energy equal to 1 eV. Therefore, Ev is a unit of energy, and it is especially used in contexts involving subatomic particles and quantum mechanics.
The correct answer is: Energy.
