Chem Final definitions

Atomic Radius

The measurement from the nucleus to the valence electrons

Ionization

The minimum energy required to remove an electron from a gaseous atom or ion

Electronegativity

Is a measurement of how strongly an atom attracts to electrons when a chemical bond is formed.

Nuclear charge

Charge of the nucleus, that comes from protons

Metallic Character

Refers to the chemical properties of metals by how easily an atom loses its electrons from a positive ion (cation)

Isotope

All atoms of the same element contains the same contain the same number of protons, but different number of neutrons

Ion

Is a atom or molecule that has an electrical charge because it has gained or lost one or more electrons

Cation

Is formed with a positive charge, loss of electron

Anion

Is formed with a negative charge, gain of electron
