Atomic Structure

Atomic Orbital

• A model that describes the likelihood, or probability, of finding an electron at a specific location and position around the nucleus

• The arrangement of an element’s electrons in various orbitals around the nucleus to achieve the lowest energy state

• One or more atomic orbitals that have different shapes and energies, represented by the specific letters s, p, d, and f.

• Any of two or more forms of an element with the same number of protons in the nucleus but different numbers of neutrons

Electron Configuration

• The arrangement of an element’s electrons in various orbitals around the nucleus to achieve the lowest energy state

• The energy level represented by the quantum number n, where each period of the periodic table represents a different principal energy level represented by its corresponding quantum number (n = 1, 2, 3…)

• The total number of protons and neutrons in the nucleus of an atom

• Any of two or more forms of an element with the same number of protons in the nucleus but different numbers of neutrons

Energy Sublevel

• One or more atomic orbitals that have different shapes and energies, represented by the specific letters s, p, d, and f.
