a. True
Explicación
## Step 1The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. For Carbon, the atomic number (which represents the number of protons) is 6.## Step 2Given that the mass number is 13, we can find the number of neutrons by subtracting the number of protons from the mass number.### **Number of neutrons = Mass number - Number of protons**## Step 3Substituting the given values into the formula, we get:### **Number of neutrons = 13 - 6 = 7**## Step 4Therefore, the statement "If the mass number of Carbon is 13 it has 7 neutrons" is true.
