Question

consider the isotope notation shown.
$\ce{^{13}_{6}c}$
how many neutrons are in the
particle?
6
19
13
7

Explanation:

Step1: Recall neutron calculation formula

The number of neutrons (\(n\)) in an atom is calculated by the formula \(n = A - Z\), where \(A\) is the mass number (top number in isotope notation) and \(Z\) is the atomic number (bottom number in isotope notation).

Step2: Identify \(A\) and \(Z\) for \(\ce{^{13}_{6}C}\)

For \(\ce{^{13}_{6}C}\), the mass number \(A = 13\) and the atomic number \(Z = 6\).

Step3: Calculate number of neutrons

Using the formula \(n = A - Z\), substitute \(A = 13\) and \(Z = 6\): \(n = 13 - 6 = 7\).

Answer:

7 (corresponding to the option with 7)
