How many neutrons does lutetium have
WebBohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have. Figure 2 contrast the Bohr diagrams for lithium, fluorine and aluminum atoms. The shell closest to the nucleus is ... WebHow many neutrons does a lithium atom have? Scientist Chadwick discovered neutrons in 1932. It is located in the nucleus at the center of the atom. The neutron is a charge-neutral particle and it is expressed by n. The charge of a neutron is 0 and the relative charge is also 0. The mass of the neutron is 1.674 × 10 −27 kg.
