Periodic table of density

Interactive periodic table of element density in g/cm³ (gases at 0 °C). ElementWorks is a free interactive periodic table: hover an element to preview it, click it for its full card, or pick another view from the Show menu.

Periodic table of density explained

Density is mass per unit volume. This table gives density in grams per cubic centimeter; gases are listed at 0 °C and 1 atm, so their values are very small. Osmium and iridium are the densest known elements near 22.6 g/cm³, while hydrogen is the least dense element. Density depends on both atomic mass and how closely atoms pack.

Highest values

  1. Osmium (Os): 22.59 g/cm³
  2. Iridium (Ir): 22.56 g/cm³
  3. Platinum (Pt): 21.45 g/cm³
  4. Rhenium (Re): 21.02 g/cm³
  5. Neptunium (Np): 20.45 g/cm³

Lowest values

  1. Hydrogen (H): 0.08988 g/cm³
  2. Helium (He): 0.1786 g/cm³
  3. Lithium (Li): 0.534 g/cm³
  4. Potassium (K): 0.862 g/cm³
  5. Neon (Ne): 0.9002 g/cm³

Frequently asked questions

Which element is the densest?

Osmium, at about 22.59 g/cm³, with iridium almost identical at 22.56 g/cm³.

Which element is the least dense?

Hydrogen gas, at about 0.00009 g/cm³. Helium is the next lowest.

Why are gas densities so low?

Gas atoms or molecules are far apart, so a given volume contains very little mass compared with a solid or liquid.
