Answer

Explanation:

Step1: Recall atomic number definition

The atomic number of an element is the number of protons. For hydrogen ($H$), the atomic number is 1, so the answer for the number of protons is B. 1.

Step2: Identify mass number

The mass number is given as 1 in the isotope notation $^{1}H^{-1}$, so the answer for the mass number (number of nucleons) is B. 1.

Step3: Calculate number of neutrons

Number of neutrons = Mass number - Atomic number. So, $1 - 1=0$. The answer for the number of neutrons is A. 0.

Step4: Determine number of electrons

Since it is an anion with a charge of - 1 and the number of protons is 1, the number of electrons = number of protons+ magnitude of charge. So, $1 + 1=2$. But this is wrong. In fact, for $H^{-1}$, number of electrons is 2. There is no correct option for this wrong - formatted question in the given choices. But if we assume the correct isotope notation is $^{1}H^{-}$, number of electrons is 2.

Step5: Identify charge

The notation $^{1}H^{-1}$ (should be $^{1}H^{-}$) indicates a charge of - 1. So the answer for the charge is F. -1.

Answer:

  1. B. 1
  2. B. 1
  3. A. 0
  4. (No correct option in given choices, should be 2 for $H^{-}$)
  5. F. -1
