Valence Electrons and Noble Gas Notation

These flashcards cover key terms and definitions related to valence electrons, noble gas notation, and their significance in chemistry.

Valence Electrons

Electrons in the atom’s outermost orbitals that determine its chemical properties.

Electron-Dot Structures

Representations that consist of the element’s symbol surrounded by dots representing the valence electrons.

Noble Gas Notation

A shortened method of writing electron configurations using the nearest noble gas as a reference.

Chemical Properties

Characteristics that determine how an element reacts with other substances.

Stable

Describes the condition of an atom when its outer energy level is fully filled with electrons.

Electron Configuration

A representation of the arrangement of electrons in an atom.

Atomic Number

The number of protons in the nucleus of an atom, determining the element's identity.

Group (Periodic Table)

A column of elements in the periodic table that share similar chemical properties.
