1. Periodic Table ElementAtomic Number Atomic Mass Number protonsNeutronsElectrons Copper Magnesium Silicon Aluminum Sulfur Chlorine Oxygen Fluorine Sodium Carbon-14 isotope Oxygen -18 isotope Atomic Number Symbol Mass number… round to nearest whole number Outer electrons HINT!!! To find neutrons you take (mass# - protons) 1.What atomic particle determines the identity of the substance 2.How can you always tell how many electrons are in the outer shell 3.Elements in the same group always share the same number of?

2. Build an ATOM! 1.Revisit what we learned yesterday… try to do these on your own 2.Remember all neutral atoms must have the same # of protons(atomic number) and electrons 3.Isotopes have the same # of protons as normal element but extra neutrons 4.Command- shift-4 and place a screenshot of each finished atom next to it.
