What is the element with104 neutrons?
Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The atomic number represents the number of Protons and electrons in an atom, the mass number can be found by rounding the atomic mass. If you subtract the # of protons from the total it will tell you how many particles , or neutrons, are left in the nucleus of the atom.. The atomic mass of Lu is 174.967 amu Therefore 175 (total particles) -71 (proton particles)= 104 Neutron particles.
