  19. Quiz • 1. T or F, an ion is an atom with more or less electrons than protons. • 2. T or F, covalent bonds form when atoms share electrons. • 3. T or F, both gases and liquids are fluids. • 4. T or F, a gel is a solution of a gas in a liquid. • 5. T or F, hydrocarbons are held together by ionic bonds.
