검증된 단계별 안내1
Understand that covalently bonded compounds are formed when atoms share electrons to achieve stability.
Recall that the smallest unit of a covalently bonded compound that retains its chemical properties is called a molecule.
Differentiate this from ionic compounds, which are composed of ions and are represented by formula units.
Recognize that atoms are individual elements, not units of compounds, and ions are charged species, not neutral units of covalent compounds.
Conclude that the correct term for the units making up covalently bonded compounds is 'molecules'.
