Question

Quizplus · Accepted Answer

A molecule is a group of two or more atoms held together by a covalent bond. Ionic compounds are composed of ions, not covalently bonded atoms. A unit could refer to various things and is not specific to a group of atoms held together by a covalent bond. The nucleus is the central core of an atom and is not a group of atoms held together by a covalent bond. A formula is a representation of a molecule or compound but is not the actual group of atoms held together.
