COMMENTS
The densities are measured at standard atmospheric pressure. The densities of astatine (85), francium (87), fermium (100) and above are only estimated due to the short half-life of these elements. - Jianing Song, Sep 30 2018

EXAMPLE
The elements with the lowest densities are hydrogen (1), helium (2), neon (10), etc.
