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 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’.
