What is the difference between metals and non-metals?
Metals lose electrons easily (low ionization energy, form cations); non-metals gain electrons (high electronegativity, form anions).
Metals lose electrons easily (low ionization energy, form cations); non-metals gain electrons (high electronegativity, form anions). A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
