• atomic orbital

A ______ is the amount of energy an electron needs to move levels.

• Quantum

• Quantum Mechanical Model

• Energy Levels

• Aufbau Principle

_______ determines the allowed energies an electron can have and how likely it is to find the electron in various locations around the nucleus. Was a result of Schrodinger's mathematical equation describing the behavior of the electron in a hydrogen atom.

• Quantum Mechanical Mode

• Quantum

• Hund's Rule

• Pauli Exclusion Principal

An ______ is the region of space in which there is a high probability of finding an electron.

• Atomic orbital

• Energy Levels

• Quantum

• Aufbau Principle

Electrons occupy the orbitals of lowest energy first.

• Aufbau Principal

• Hund's Rule

• Pauli Exclusion Principal

• Exceptional Electron Configurations

An atomic orbital may describe at most two electrons. To occupy the same orbital, two electrons must have opposite spins.

• Pauli Exclusion Principal

• Hund's Rule

• Aufbau Principal

• Quantum Mechanical Model

______ states that one electron will enter each orbital until all the orbitals contain one electron with the same spin direction. Electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible.

• Hund's Rule

• Aufbau Principal

• Pauli Exclusion Principal

• Energy Levels

Half-filled sublevels are not as stable as filled sublevels, but they are more stable then other configurations.

• Hund's Rule

• Quantum Mechanical Model

• Atomic Orbital

The ways in which electrons are arranged in various orbitals around the nuclei of atoms are called _____.

• Electron Configurations

• Energy Levels

• Aufbau Principle

• Atomic Orbital
