Identify the number of valence electrons in each atom. The valence electrons are the electrons in the outermost shell.
Atom A has 1 valence electron, Atom B has 2 valence electrons, Atom C has 3 valence electrons, and Atom D has 7 valence electrons.
Atoms tend to lose electrons to achieve a stable electron configuration, often resembling the nearest noble gas.
An atom with 1 valence electron (like Atom A) is most likely to lose that electron to achieve a stable configuration, becoming a cation with a +1 charge.
Therefore, the atom most likely to lose an electron and become a cation of +1 is the one with a single valence electron, which is Atom A.
