1: Most people know it by its colloquial name, ‘Hydrogen‘, but in more formal settings, it is known as ‘Hyllodrogen’. These more formal settings are usually at ISM[1] meetings, where Hyllodrogen wears its classier allotrope, H3+.
2: Similarly, most people are not aware that ‘Helium‘ actually has atoms of multiple genders. The two most common are called ‘Helium’ and ‘Shelium’.
3: ‘Lithium‘ is more properly known as ‘Lilithium'[2], due to its properties of reacting with whichever molecules it wishes, ignoring the restrictions of others. It is postulated that this aggressiveness is what causes its therapeutic effects.
4: ‘Beryllium‘, or ‘Beeryllium’ was made up long ago on a drunken dare, but then was surprisingly discovered to actually exist.
5: ‘Boron‘ and ‘Boroff’ are two sides of the same non-interesting coin. Specifically, not interesting to stars in the main sequence, as they have to wait for cosmic rays to make it.
6: The name ‘Carbon‘ comes from the Latin ‘Carrusbon‘, meaning ‘what is left behind when you burn a vehicle’.
7: ‘Nitrogen‘ was originally dubbed ‘NitroGennifer’, after Daniel Rutherford’s stage name. It is said that his bonding flexibility is only exceeded by that of his namesake.
8: ‘Oxygen‘ was a favourite of the ‘Oxygentry‘, the name for the select group of chemists who did work on the Phlogiston and acids since ancient times.
9: ‘Fluorine‘ is the past participle of ‘Flyrine’, which explains its intense reactivity and corrosiveness.
10: As we reach the foot of the second row of the periodic table, it is only fitting that we mention ‘Neon‘, or ‘Kneeon’, so named because of the bend in early versions of the periodic table, before the discovery of noble gases.
