About the columns

Atomic mass is in unified atomic mass units (u). For elements with no stable form, the mass of a long-lived form is given.
State is the state at room temperature. For the heaviest elements it is a prediction.
Melts at / Boils at are in degrees Celsius at normal pressure.
Density is in grams per cubic centimetre. For gases it is the density of the gas at 0 °C.
Electronegativity is on the Pauling scale.
Discovered: "Ancient" means the element was known before written records of its discovery.

"No value" means the property has not been measured, usually because only a few atoms of the element have ever existed.
