What four elements make up 96% of the human body?
Ans: Carbon, Hydrogen, Oxygen, and Nitrogen
Atoms
Ans: Unique building blocks for each element, smallest particles of an
element with properties of that element
Planetary Model
Ans: Simplified and outdated because it incorrectly depicts electrons in
orbits, fixed circular paths
Orbital Model
Ans: Current model used that depicts orbitals, probable regions where an

Atomic Number
Ans: The number of protons in the nucleus of an atom
Mass Number
Ans: The total number of protons and neutrons in the nucleus of an atom
