How do you estimate the number of neutrons in the atoms of an element?

The number of neutrons in the nucleus of an atom of any isotope of an element is equal to the "atomic mass number", which is usually stated in a number immediately after a hyphen at the end of the element name in the name of the isotope, minus the atomic number. Because most elements have more than one stable isotope, the average number of neutrons in the mixture of isotopes of an element that occurs naturally is usually not an integer.
