Periodic TableAtomic number - correct answer ✔✔The number of protons in the nucleus of the atom
Atomic weight - correct answer ✔✔The mass of the protons and neutrons in the atom (electrons

Atomic Weight - correct answer ✔✔Based on the number of neutrons the majority of the element's
atoms have.
Isotopes - correct answer ✔✔Different atoms of an element can have a different amounts of neutrons
If there is a different number of neutrons than the average number for that element, the atom is an
isotope.
Calculating Numbers of Particles - correct answer ✔✔# of Protons = Atomic #
# of Electrons (usually) = Atomic #
# of Neutrons = Atomic Mass - Atomic #
Electron Energy Levels - correct answer ✔✔Electrons exist in region around the nucleus called energy
levels.
Each energy level holds a certain number of electrons.
Each period (row) on the periodic table represents a new energy level.
What do the different energy levels actually look like? - correct answer ✔✔Energy levels can be split into
"orbitals".
Each orbital contains two electrons. This is what it looks like when you put it all together.
