When a helium atom loses an electron, it becomes:

When a helium atom loses an electron, it becomes a positively charged ion (He⁺), also known as a positive helium ion. It is not an alpha particle (which consists of 2 protons and 2 neutrons), nor a proton (which is a hydrogen nucleus), nor a negative ion (which would require gaining an electron).
