Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

COMMENTS

From Jianing Song, Sep 30 2018: (Start)

Helium (2) cannot solidify at standard atmospheric pressure, its melting point (0.95 K) is measured at 2.5 MPa. Carbon (6) and arsenic (33) cannot liquify at standard atmospheric pressure, their melting points (4600 K and 1090 K) are measured at 10.8 MPa and 2.8 MPa, respectively.

The melting points of astatine (85), francium (87), fermium (100) to rutherfordium (104) are only estimated due to the short half-life of these elements. (End)
