  1. Chemistry 8.1

  2. 8.1 Molecules and Molecular Compounds • A molecule: atoms joined together by covalent bonds (shared). Neutral. • A diatomic molecule: a molecule consisting of two atoms. Rule of 7’s.

  3. 8.1 Molecules and Molecular Changes • Molecular compounds tend to have relatively lower melting and boiling points than ionic compounds.

  4. 8.1 Molecular Formulas • A molecular formula is the chemical formula of a molecular compound. • shows how many atoms of each element and types of elements

  5. 8.1 Molecular Formulas

  6. 8.1 Molecular Formulas • Formulas of Some Molecular Compounds

  7. 8.1 Section Quiz. • 8.1.

  8. 8.1 Section Quiz. • 1. Compared to ionic compounds, molecular compounds tend to have relatively • low melting points and high boiling points. • low melting points and low boiling points. • high melting points and high boiling points. • high melting points and low boiling points.

  9. 8.1 Section Quiz • 2. A molecular compound usually consists of • two metal atoms and a nonmetal atom. • two nonmetal atoms and a metal atom. • two or more metal atoms. • two or more nonmetal atoms.

  10. 8.1 Section Quiz • 3. A molecular formula shows • how many atoms of each element a molecule contains. • a molecule's structure. • which atoms are bonded together. • how atoms are arranged in space.
