Solution
Solution Steps
Step 1: Identify the Chemical Species
The chemical species given is \(\mathrm{H}^{-}\). This notation represents a hydrogen atom that has gained an extra electron, resulting in a negative charge.
Step 2: Determine the Correct Name
In chemistry, when a hydrogen atom gains an electron, it forms a negatively charged ion known as a hydride ion. This is because the term "hydride" is used to describe hydrogen in its anionic form.
Final Answer
The correct name for \(\mathrm{H}^{-}\) is \(\boxed{\text{hydride}}\).
