non-metal As far as elements are concerned, a nonmetal is simply an element that does not display the properties of a metal. It is not defined by what it is, but by what it is not. It doesn't look metallic, can't be drawn into a wire or pounded into shape or bent,
Atomic Number the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
electron a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
ion an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
proton stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
metal a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g., iron, gold, silver, copper, and aluminum, and alloys such as brass and steel)
period A period is the name given to a horizontal row of the periodic table. The periodic table has seven periods. Period 1 contains only two elements: hydrogen and helium.
