Formulas and Equations

1. Handout: Formulas and Equations Note Packet
2. Elements
   1. The names of the elements are given on the periodic table.
   2. Formulas are written differently depending on the element.
      1. The formula for most elements is just its symbol. For example, Na for sodium or Xe for xenon.
      2. Some elements naturally come in diatomic molecules. When expressing this element in its pure form we would write a formula indicating this state. There are seven diatomic elements: H₂, N₂, O₂, F₂, Cl₂, Br₂, and I₂. You should memorize these.
