Question

how many neutrons are in 1 atom of carbon - 13?

Explanation:

Step1: Recall the formula for neutrons

The formula for the number of neutrons \(N\) in an atom is \(N = A - Z\), where \(A\) is the mass number and \(Z\) is the atomic number.

Step2: Identify \(A\) and \(Z\) for Carbon - 13

For Carbon - 13, the mass number \(A=13\). From the periodic table, the atomic number of carbon \(Z = 6\) (since carbon is the 6th element).

Step3: Calculate the number of neutrons

Substitute \(A = 13\) and \(Z=6\) into the formula \(N=A - Z\). So \(N=13 - 6=7\).
