Number of neutrons = Mass number - Atomic number
According to the Periodic Table, the "Mass number" of lutetium is 174.97, and the "Atomic number" is 71. Therefore,
Number of neutrons = 174.97 - 71 = 103.97 neutrons or approximately 104 neutrons.

What city was Lutetium named after?
Lutetium was proposed as the name for the element with atomic number 71 by French scientist Georges Urbain, one of its several discoverers on 1907. It was adopted as the official name by the The Commission on Atomic Mass in 1909.
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.
What is the period and group for lutetium?
Lutetium is a chemical element with the symbol Lu and atomic number of 71. It has a period of 6 and belongs in the Lanthanide group.
What is the atomic number and atomic mass number for an isotope of Lu with 106 neutrons?
The atomic number of an element is the number of protons in the nucleus. For the element Lu (lutetium), the atomic number is 71. The atomic mass number is the sum of the number of protons and neutrons in the nucleus. Therefore, an isotope of Lu with 106 neutrons would have an atomic mass number of 177 (71 protons + 106 neutrons = 177).
What is lu on the periodic table?
