Answer 1

`"My word........."`

Explanation:

A chemical element is one of the hundred or so substances that CANNOT be chemically interconverted or broken down into simpler substances. Elemental hydrogen occurs as a bimolecular gas under normal conditions, i.e. `H_2`. Some chemists refer to it as `"dihydrogen"` in order to emphasize its molecularity. Apart from the Noble Gases, all the elemental gases are bimolecular: i.e. `"dihydrogen"`; `"dinitrogen"`; `X_2` etc.
