Periodic table chart

Density chart of the elements

Density is mass per unit volume, shown in grams per cubic centimetre (g/cm³). Solids and liquids are measured near room temperature and gases at 0 °C and normal pressure, which is why gas values are so small.

No data

Colours use a logarithmic scale because the values span several orders of magnitude.

Values marked * are predictions for superheavy elements made only a few atoms at a time. They are left out of the colour scale and the rankings.

The trend

Density rises down most groups, as atoms gain mass faster than they gain volume, and peaks in the middle of the sixth period, where osmium and iridium are the densest elements known. Hydrogen is the least dense. Because gases are around a thousand times less dense than solids, the colours use a logarithmic scale.
