True.
Diatomic ions = O2, H2, He2, etc.

False!
The answer is false because an ion is not an atom and does not contain atoms. Ions are made up of chemical "formula unit(s)" from their respective constituent elements. An ion is electrically charged, positive or negative.
Atoms are electrically Neutral, as there is no net charge, positive or negative, because the number of protons and electrons in an atom are equal.
Ions are usually formed by stripping atoms of one or more of their electrons. When that happens, the atom is then called an "ion" as it is no longer neutral and its behaviour in chemical reactions is different from that of the original atom!
So, a more accurate way to state it would be: "A monatomic ion is derived from only one atom" e.g Na+ or Fe^3+, etc.
The word "mono" refers to 1, but that should not trick you to think that an ion is an atom!
I would rather not use the word "contains" for a single ion, as it is only one electrically charged particle.

true, because mono=1
