Answer

Explanation:

Step1: Recall atomic number definition

The atomic number of hydrogen is 1, which is equal to the number of protons. So the answer for the number of protons is 1 (B).

Step2: Identify mass - number

The mass number is given as 2 in the isotope notation (^{2}H^{ + 1}), so the answer for the mass number is 2 (C).

Step3: Calculate number of neutrons

The formula for the number of neutrons (n) is (n=A - Z), where (A) is the mass number and (Z) is the atomic number. Here (A = 2) and (Z=1), so (n=2 - 1=1) (not in the given options, there may be a mis - typing in the problem setup, but based on correct calculation).

Step4: Determine number of electrons

Since it is a (H^{+1}) ion, a neutral hydrogen atom has 1 electron and losing 1 electron gives 0 electrons. So the answer is 0 (A).

Step5: Identify charge

The notation (^{2}H^{+1}) clearly shows a charge of + 1. So the answer is 1 (B).

Answer:

  1. B. 1
  2. C. 2
  3. (Based on correct calculation should be 1, not in options)
  4. A. 0
  5. B. 1
