Question

33 multiple choice 1 point how many neutrons are in sulfur - 34? 18 34 16 20

Explanation:

Step1: Identify atomic number of sulfur

From the periodic - table, the atomic number of sulfur (S) is 16. The atomic number ($Z$) is the number of protons in an atom.

Step2: Recall the relationship between mass number and neutrons

The mass number ($A$) of sulfur - 34 is 34. The formula to find the number of neutrons ($N$) is $N=A - Z$.

Step3: Calculate the number of neutrons

Substitute $A = 34$ and $Z = 16$ into the formula: $N=34−16$.
$N = 18$.

Answer:

18
