How much neutrons, protons and electrons does hydride have

if you're talking about hydrogen then it has Number of Protons 1Number of Neutrons 0 Numbers of Electrons 1

Answer: Neutrons = 0

Protons = 1

Electrons = 2

Explanation: The formula for hydride is H - it is an ion.

The number of protons is the atomic number of Hydrogen which is 1.

The number of neutrons can be calculated by subtracting the Atomic mass to its Atomic number

So 1 - 1 = 0

Since it is an ion, hydride gains 1 electron as indicated by its charge so the number of electrons is equal to 2.
