An atom of hydrogen loses its electron. What is its charge

Final +1

Explanation/Reasoning:

Because hydrogen is an atom (not an ion), you'll write it as H (not H+). Hydrogen (H) has one proton and one electron, so if it loses its electron, it will only have one proton. Therefore, it becomes an ion of H+. This means that the charge will be +1.
