The number of electrons presents in H+ is

  • A.Zero
  • B.One
  • C.Two
  • D.Three

Answer: A

The \(\mathrm{H^+}\) ion contains no electrons.

A hydrogen atom has one proton and one electron; removing that electron leaves a bare proton. This is why \(\mathrm{H^+}\) never exists free in solution - it attaches at once to a water molecule to give the hydronium ion \(\mathrm{H_3O^+}\).
