Question

In order to calculate how many neutrons are in an atom, you must subtract the mass number from the number of protons? Neutrons = Mass # - Protons Question 6 options: True False

Answer 1

True.

Step-by-step explanation:

The mass number of an atom can be calculated using no of protons and the no of neutrons.

Mass number = no of protons + no of neutrons

We can rearrange the above formula to find the no of neutrons as follows :

no of neutrons = Mass number - no of protons

or

Neutrons = Mass - protons.

Hence, the given statement is true.
