An atom becomes an ion through:
Losing electrons
Gaining electrons
Both options are correct
None of them are correct
Ionic compounds are made up of:
ions
only cations
only anions
isotopes
Why do all bonds form?
so the number of protons equals the number of electrons
so an atom can become unstable
to fill the outermost energy level
Why do atoms share electrons?
to increase their atomic number
to become ions
to obtain noble gas electron configuration
to become less polar
