You are presented with the question "what can an ion have if it loses an electron?" and the following answer choices: 
- It becomes dormant
 - negative charge
 - kinetic energy
 - energy barrier
 - heat energy
 - Electrical energy
 - hydrogen and oxygen
 - activation energy

Now knowing that if a neutral atom loses an electron then an atom with a negative charge will be formed and ions are neutral atoms, choose the best answer.
