1. getting started: building molecules

Explanation:

1. An atom is the fundamental unit that makes up an element, retaining all the chemical properties of that element.
2. Molecules are formed when two or more atoms connect via chemical bonds.
3. Covalent bonds are defined by atoms sharing valence electrons to achieve stability, while ionic bonds form when one atom transfers electrons to another, creating charged ions that attract.

Answer:
