Atoms which lose electrons and become electrically charged are called . fussion particles
ions
electrolytes
fission particles

ions

Explanation:

When an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. Positive ions are called cations, and negative ions are called anions. Cations and anions are attracted to each other.

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. not an atom.
