Question

what is the atomic symbol and mass number for an atom containing 50 protons and 64 neutrons? answer:

Explanation:

Step1: Determine the atomic number

The atomic number \(Z\) is equal to the number of protons. Given there are 50 protons, so \(Z = 50\).

Step2: Determine the mass number \(A\)

The mass number \(A\) is the sum of protons and neutrons. So \(A=50 + 64=114\).

Step3: Find the element symbol

Looking at the periodic table, the element with atomic number \(Z = 50\) is Tin (\(Sn\)).

Answer:

B. \(^{114}_{50}Sn\)
