A lithium atom contains 3 protons, 4 neutrons and 3 electrons. What would be formed it one proton if one proton is added to this atom

Answer: Beryllium ion (Be+)

Explanation:

Addition of one proton to Li would lead to formation of Beryllium ion since Beryllium contains 4 protons and 4 electrons to counter the charges and make the element neutral. But in this case, Be + is formed to show a deficit of one electron (e-).
