I want to know the answer to the following question:
What charge does hydrogen display in ionic compounds when it is called a hydride?
All the background I'm provided with is that "In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) when it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+.". Is that enough to answer the question?
