Symbol Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. 38 protons, 38 electrons, 52 neutrons. by crazylilduck 31-10-2009 00:07, Post 49 2). If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

They are equal to 16, 16 and 18, respectively. numQuotes: 69, On the other hand, the masses of protons and neutrons are fairly similar, although technically, the mass of a neutron is slightly larger than the mass of a proton. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoesradioactive decay.
