Today, the Fast Plant was due, so everyone make sure that you get that in. Also, today we continued some Basic Chemistry Notes (We couldn't do much because of the late arrival). One important note is that molecules, a new term, are groups of atoms that are joined together through chemical bonds. The big thing was the main difference between ionic bonds and covalent bonds, which are both tyes of chemical bonds. Remember that: Ionic bonds involve the transfer of electrons. And covalent bonds involve the sharing of electrons between atoms. Examples: ionic bond = table salt molecules, and covalent bonds = water molecules As a general note: remember that atoms are the basic unit of matter. Elements are substances that are made of only one type of atom. Compounds are substances that are made up of two or more elements. And molecules are particles that are made up of two or more different types of atom. Next scribe = Claire
