Question

how many electrons does this ion have? * 10 points
34
16 s - 2
18
how many neutrons does this atom have? (only type in numbers) * 10 points
34
16 s - 2
18

Explanation:

Step1: Recall atomic number property

The atomic number of sulfur (S) is 16, which means a neutral sulfur atom has 16 electrons.

Step2: Consider ion charge

The ion has a - 2 charge, indicating it has gained 2 electrons.

Step3: Calculate electron number

The number of electrons in the ion is $16 + 2=18$.

Step4: Recall mass - number and atomic - number relationship for neutrons

The mass number is 34 and the atomic number is 16. The number of neutrons is calculated by subtracting the atomic number from the mass number.

Step5: Calculate neutron number

The number of neutrons is $34 - 16 = 18$.

Answer:

How many electrons does this ion have? 18
How many neutrons does this atom have? 18
