An element has an atomic number of 8 and a mass number of 16. How many neutrons does this element have?
24
16
8
32
Correct answer is C
The atomic number of an element is equal to the number of protons, which in this case is 8. The mass number is the total number of protons and neutrons, which is 16. To find the number of neutrons, we subtract the atomic number from the mass number:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 16 - 8
Number of neutrons = 8
So, the element has 8 neutrons.
