The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gas state.

# data[].attributes.body
Orbitals are  each of the actual or potential patterns of electron density that may be formed in an atom or molecule by one or more electrons, and that can be represented as a wave function.

Protons are a stable particle occurring in all atomic nuclei, with a positive charge equal in magnitude to that of an electron.

# data[].attributes.body
Electrons are a stable particle occurring in all atomic nuclei, with a positive charge equal in magnitude to that of an electron, but of opposite sign.
