Question

for an isotope of silver had atomic number of 47 and mass number of 108. the number of protons and neutrons, are

Explanation:

Step1: Recall proton - atomic number relation

The atomic number is equal to the number of protons. Given atomic number = 47, so number of protons = 47.

Step2: Calculate number of neutrons

The mass number is the sum of protons and neutrons. Let the number of neutrons be $n$. We know mass number $A=108$ and number of protons $p = 47$. Using the formula $A=p + n$, we get $n=A - p$. Substituting values, $n=108 - 47=61$.

Answer:

Number of protons: 47; Number of neutrons: 61
