Question

which of the following is most likely to form a cation? alkaline earth metals non - metals nobel gases halogens

Explanation:

Cations are positively - charged ions formed by losing electrons. Alkaline earth metals have 2 valence electrons and tend to lose them to achieve a stable electron configuration, forming cations. Non - metals gain electrons to form anions, noble gases are stable and do not easily form ions, and halogens gain 1 electron to form anions.

Answer:

Alkaline earth metals
