Valence Shells

Valence shells refer to the outermost shell of an atom that contains electrons. These electrons are involved in the formation of chemical bonds with other atoms. The configuration of electrons in the valence shell determines the chemical properties of an element.

The valence shell can be represented using the electron configuration notation, which describes the distribution of electrons in the various subshells within the shell. The notation follows the pattern of "1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s," where the numbers represent the principal quantum number and the letters represent the subshells within the principal quantum level.

The concept of valence shells is fundamental to understanding the behavior of elements in chemical reactions and the formation of compounds.
