Question

an atom of sulfur (s) has a mass number of 34 and an atomic number of 16. how many neutrons does it have? multiple choice 1 point

Explanation:

Step1: Recall the formula for neutrons

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

Step2: Identify values of A and Z

For sulfur, $A = 34$ (mass number) and $Z = 16$ (atomic number).

Step3: Calculate the number of neutrons

$N=34 - 16=18$.

Answer:

18
