Question

which of the following elements would form a cation? oxygen flourine magnesium nitrogen covalent bonds are normally formed when electrons are shared between a metal and a nonmetal electrons are shared between two nonmetals electrons are transferred from a metal to a nonmetal electrons are transferred from a nonmetal to a metal

Explanation:

For the first question:

• Cations are positively - charged ions. Metals tend to lose electrons to form cations. Magnesium (\(Mg\)) is a metal. Oxygen (\(O\)), fluorine (\(F\)), and nitrogen (\(N\)) are non - metals. Non - metals tend to gain electrons to form anions.

For the second question:

• Covalent bonds are formed by the sharing of electrons. Non - metals have similar electronegativities, so they share electrons to achieve a stable electron configuration. When electrons are transferred (from a metal to a non - metal), ionic bonds are formed.

Answer:

First question: Magnesium.
Second question: electrons are shared between two nonmetals.
