Answer:
Stable, Cation, Donor Atom
Explanation:
When an atom has less than 4 electrons in its valence shall, it tends to lose those electrons to becomes stable. Because an atom becomes stable when its valence shell is complete. So, when it loses the electrons its valence shell becomes complete. Also, after the loss of the electrons a positive charge is developed on the atom and it becomes an cation or donor atom.
Hence, there can be multiple answers to this question.
Atoms with fewer than 4 valence electrons want to give their electrons to become Stable, Cation, Donor Atom.
