Neutral Cations are typically formed by which species?

Neutral Cations are typically formed by which species?

• A. Halogens
• B. Group 1 metals, Group 2 metals, metals with a +1 charge
• C. Noble gases
• D. Transition metals with variable oxidation states

Answer: (B)

Metals tend to lose electrons to reach a stable configuration, so they form positively charged ions (cations). The most straightforward, commonly formed cations come from the left side of the periodic table: Group 1 metals (alkali metals) loss of one electron gives a +1 charge, and Group 2 metals (alkaline earth metals) loss of two electrons gives a +2 charge. Some other metals can also form a +1 cation, but not as uniformly as the Group 1 and Group 2 elements. Halogens are nonmetals that gain an electron to form a negatively charged ion (an anion), so they aren’t the typical source of simple cations. Noble gases are very unreactive and do not readily form ions under ordinary conditions. Transition metals can form cations as well, but their charges vary widely (not just +1 or +2), so they’re less representative of the simple, common cations described here. Thus the species that most often form basic, straightforward cations are the Group 1 and Group 2 metals, plus metals that commonly exhibit a +1 charge.
