CatalystPretend that you’re the size of an atom, observing a reaction between a potassium atom, and a fluorine atom. Write an account of the formation of an ionic bond as the atoms react. Tell what happens to the valence electrons on each atom and how each atom is changed by losing or gaining electrons.

Pretend that you’re the size of an atom, observing a reaction between a fluorine atom, and another fluorine atom. Write an account of the formation of an covalent bond as the atoms react. Explain what happens as the two atoms come together.

Exit Ticket

Of the substances that you observed today (Distilled water, Table Salt, Sugar, Vegetable Oil, Isopropyl Alcohol), which do you think are held together by ionic bonds, and which do you think are held together by covalent bonds?

Catalyst1. Explain how metal atoms form metallic bonds in crystals.2. What role do the valence electrons play?3. How does a metallic bond differ from an ionic bond?
