The Atomic Model
Quantum
A fixed amount
Valence Electrons
Electrons in the outermost shell of the atom, capable of taking part in chemical reactions
Photon
Fixed amounts of energy in light
Ground State
Lowest energy position of an electron in an atom
Quarks
Particles that make up neutrons and protons, classified as colors and flavors
Electron Orbits
Shell Electrons n = 1 2 n = 2 8 n = 3 18 n = 4 32 n = 5 50 n = 6 72 n = 7 98
Orbital
The area around the nucleus of an atom where the probability of finding an electron is greatest
Atomic Mass
The mass of the protons plus the mass of the neutrons in the nucleus of an atom
Atomic Number
The number of protons in the nucleus of an atom
