Valence Electrons and Their Properties

These flashcards cover key concepts related to valence electrons, their properties, and the significance of electron configuration in chemical behavior.

Valence Electrons

The electrons in the outermost shell of an atom that determine its chemical properties.

Valence Shell

The outermost shell of an atom, which contains valence electrons.

Chemical Properties

Characteristics of an element that depend on the arrangement of its electrons.

Group Number

The number in the periodic table that indicates the number of valence electrons for main group elements.

He Exception

Helium is an exception in group 8A, having only 2 valence electrons instead of the expected 8.

Electron Configuration

The arrangement of electrons in an atom, particularly in relation to the valence shell.
