- Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
- The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
- Do Now– Get out your science notebook and open to page 72. Get out the Periodic Table Elements 1-20 handout. Use your periodic table to tell me the name, atomic number, and the atomic mass of the element that Lia is pointing to. How many protons, electrons, & neutrons does an atom of that element have?
