When talking about ionic or covalent, we are referring to the bonds between two atoms or ions, not characterizing the whole molecule. In hydrogen peroxide, the link between the two oxygen atoms is a...
It is covalent since the difference in electronegativity is very less between the two
Covalent
Neither. Hydrogen is an element, not a compound. Though it normally occurs in the form of covalently bonded molecules.
i would think ionic due to the fact that they are a metal and a non-metal
