What is 67 on the periodic table?
What is 67 on the periodic table? 67 on the periodic table is holmium (symbol Ho), the element with atomic number 67, meaning each atom has 67 protons.
It is a soft, silvery metal in the lanthanide series (period 6, f-block) with an atomic mass of about 164.93 u, identified by Marc Delafontaine in 1878 and separated by Per Teodor Cleve in 1879, who named it after Stockholm (Holmia). Holmium has the highest magnetic moment of any naturally occurring element and is used in strong magnets, nuclear control rods and medical lasers. For a different question, see “what are the elements”.
Searches for '6 7 on the periodic table' often come from the slang '67' (said 'six seven'), a viral 2025 internet meme tied to the Skrilla song 'Doot Doot (6 7)', which Dictionary.com named its 2025 Word of the Year. The slang has no chemical meaning, but it sends many people to element 67. A separate page on this site answers “what are the 5 elements”.
Holmium is a rare earth element found in minerals such as monazite and gadolinite and in trace amounts in the Earth's crust. Its atomic number of 67 means 67 protons and 67 electrons in a neutral atom, with an electron configuration of [Xe] 4f11 6s2. The same series of answers also covers “how many groups are on the periodic table”.
It has a single stable isotope, holmium-165, which gives 165 − 67 = 98 neutrons. Holmium is a silvery solid with a melting point of about 1,461 °C and a density of about 8.8 g/cm3, and holmium oxide glass is used to calibrate spectrophotometers. In the table, holmium sits among the lanthanides, between dysprosium (66) and erbium (68).
If you were searching for something else, note that '6 7' as slang has no fixed meaning and is used as a joke or a filler word, so the periodic table answer is element 67, holmium. Because of its high magnetic moment, holmium is also used in pole pieces that concentrate strong magnetic fields. So '67' means holmium on the periodic table (the 67th element), while read as separate numbers, 6 and 7 are carbon and nitrogen.
