How do you calculate neutrons for elements in the periodic table?

Answer 1

them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element

simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element

Answer 2

To calculate the number of neutrons in an element, you subtract the atomic number (number of protons) from the Atomic Mass (nearest whole number). The atomic mass is the weighted average of the isotopes of that element found in nature. For example, for carbon, the atomic number is 6 and the atomic mass is around 12, so the number of neutrons would be 12 - 6 = 6.

Answer 3

You have to subtract the atomic mass by the atomic number

Answer 4

we can calculate the number of neutrons by deducting atomic number from atomic mass.

Answer 5

atomic mass number (written at bottom of element box) - atomic number (written at top of element box) = number of neutrons
