Question

which of the following groups of elements tend to form cations? answer: a metals b metalloids c nonmetals d noble gases e radioactive elements

Explanation:

Metals have low ionization energies and tend to lose electrons, forming cations. Metalloids have intermediate properties. Non - metals gain electrons to form anions. Noble gases are stable and do not easily form ions. Radioactive elements' ion - forming behavior depends on their metal/non - metal nature within the radioactive group.

Answer:

A. metals
