Chapter 5 Vocab, etc.

A region of space around the nucleus where an electron with a particular energy is likely to be found

• atomic orbital
• electron density
• principal energy level
• quantum

The measure of the probability of an electron being present at a specific location (shown in an electron cloud by darker shading)

• electron density
• atomic orbital
• principal energy level

NGSS.HS-PS1-1

This states that each orbital in an atom can hold at most 2 electrons, which must have opposite spins

• Pauli exclusion principle
• Hund's rule
• Aufbau principle
• quantum mechanical model

This explains the properties of atoms by treating the electron as a wave and quantizing its energy

• quantum mechanical model
• Bohr's model
• plum-pudding model
• Rutherford's nuclear model

NGSS.HS-PS4-1

The clockwise or counterclockwise motion of an electron

• electron spin
• quantum
• Hund's rule
• orbital

This states that orbitals of equal energy are occupied by one electron each before any of those orbitals are occupied by a second electron (split 'em up before you pair 'em up)

• Hund's rule
• Pauli exclusion principle
• Aufbau principle
• quantum mechanical model

Describes the most stable arrangement of electrons around the nucleus of an atom, using superscripts with sublevels

• electron configuration
• orbital diagram
• Bohr model of the atom
• quantum

This says that electrons enter orbitals of lowest energy first

• Aufbau principle
• Hund's rule
• Pauli exclusion principle

The amount of energy required to move an electron from its present energy level to the next higher one

• quantum
• orbital
• energy level
• photon
