Elements are organized based on similar characteristics into _______.
What are groups?
200
____________ are elements that do not conduct heat or electricity well.
What are non-metals?
300
This is the group that does not change in the experiment and instead is compared to the experimental group.

Describe the basic structure of an atom including the subatomic particles and their charges. Then explain how you find each of those amounts on the periodic table.
Protons-positive, neutrons- neutral, electrons-negative. Atomic number- is number of protons and electrons. Neutrons is the atomic mass minus the atomic number.
