5-8 Valence Electrons

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Boron has 3 valence electrons.

Valence electrons determine how an atom can bond with other atoms, influencing the molecule's structure and properties.

Groups 13 to 16 of the periodic table contain elements with 5-8 valence electrons.

An example is Phosphorus, which has the electron configuration 1s² 2s² 2p⁶ 3s² 3p³.

The position of an element in the periodic table indicates its number of valence electrons, with elements in the same group having the same number.

Oxygen has 8 electrons.

The atomic number indicates the number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.

Nitrogen has 5 valence electrons.

Fluorine has the electron configuration 1s² 2s² 2p⁵.
