Helium does not lose or gain electrons in chemical reactions
Helium loses two electrons to become an alpha particle in nuclear reactions.

Explanation:

Helium number two has an electron configuration of # 1s^2#
This means that Helium has only two electrons that it can lose.
Because Helium's outer valance shell is filled, Helium does not need to either lose or gain electrons to become chemically stable.

An alpha particle is a Helium atom that has had its two electrons stripped from it. creating a charged Helium particle # He_2^4 +2 # Alpha particles take place in nuclear reactions.
