Tell me the meaning of the following chemical symbols: H _ _ _ _ _ _ _ _ _ _ _ _; 6N _ _ _ _ _ _ _ _； 5s 2-_ _ _ _ _ _ _

The meaning of element symbol represents an element and an atom; Therefore, n represents nitrogen element and nitrogen atom; Adding a number before the element symbol indicates the number of atoms, so 6N represents six nitrogen atoms; Adding a number before the ion symbol indicates the number of ions, so 5S2- means five sulfur ions.

So the answer is: hydrogen, a hydrogen atom; Six nitrogen atoms; Five kinds of sulfur ions
