what happens when an atom gains an electron?\nthe atom loses a proton.\nthe atom attracts additional electrons.\nthe atom increases in atomic mass.\nthe atom becomes negatively charged.

Answer

Brief Explanations:

An atom is neutral with equal number of protons (positively - charged) and electrons (negatively - charged). When it gains an electron, there are more negative charges than positive charges, so it becomes negatively charged. Protons are not lost when an electron is gained. Gaining one electron does not necessarily attract more electrons. The mass of an electron is negligible compared to protons and neutrons, so gaining an electron does not significantly increase atomic mass.

Answer:

The atom becomes negatively charged.
