Question

task: nuclear fusion and nuclear fission
activity 2 of 5
for the isotope ( \frac{1}{1}h ) the total number of protons is
and the total number of neutrons is

Explanation:

Step1: Determine the number of protons

The subscript in the isotope notation \(_{1}^{1}H\) represents the atomic number. The atomic number is equal to the number of protons. So, the number of protons \(= 1\).

Step2: Determine the number of neutrons

The superscript in the isotope notation \(_{1}^{1}H\) represents the mass number. The formula for mass number \(A\) is \(A=\text{Number of protons}(Z)+\text{Number of neutrons}(N)\). Rearranging for \(N\), we get \(N = A - Z\). Here, \(A = 1\) and \(Z=1\), so \(N=1 - 1=0\).

Answer:

The total number of protons is \(1\) and the total number of neutrons is \(0\).
