electron configuration FC

Oxygen

A non-metal located in group 6A and essential for respiration.

Nitrogen

A gas that makes up about 78% of Earth's atmosphere and is not very reactive.

Gold

A transition metal used in jewelry and known for its resistance to corrosion.

Neon

A noble gas with 8 electrons in its outer shell, used in lighted signs and lasers.

Magnesium

A soft, silvery metal in group 2, commonly used in fireworks.

Aufbau Principle

The principle stating that electrons occupy the orbitals of lowest energy first.

Pauli Exclusion Principle

The principle stating that no two electrons can have the same set of quantum numbers.

Hund's Rule

The rule that electrons fill a subshell singly before pairing, maintaining the same spin.

Electron Configuration

The arrangement of electrons in various orbitals around the nuclei of atoms.

Atomic Number

The number of protons in the nucleus of an atom, which determines the element.

Subshells

The different energy levels where electrons reside, including s, p, d, and f.

Photosynthesis

The process by which plants convert sunlight, water, and carbon dioxide into sugars.

Electron Configuration Rules
