Explanation:
Answer:
True
Explanation:
A cation is a positively charged atom (whereas an anion is negatively charged).
Electrons are negatively charged. If an atom loses negative particles, it'll become positive.
Group 1 and 2 elements are metals. Metals lose electrons to form ions, thus metals become cations. Metals become positively charged.
They will lose all of their valence electrons to become an ion. Group numbers tell you the valance electrons of an atom.
Group 1 elements have 1 valence, which they lose to become a cation.
Group 2 elements have 2 valances, which they lose to become a cation.
