Feb 03, 2016 · Atomic number = number of protons (which, for neutral atoms, is equal to the number of electrons). Atomic symbol allows us to find the atomic number because you can just look it up on the periodic table. Atomic mass = number of protons + number of neutrons. Solutions for the Protons, Neutrons, and Electrons Practice Worksheet: Atomic.

These 18 electrons are found in the 4p (3 e-), 5s (2 e-), 4d (10 e-), and 5p (3 e-) sublevels. Notice in the figure below, the radius lanthanum is larger than lutetium. The atomic number of Lu is fourteen (14) greater than that for lanthanum. The fourteen electrons (14 e-) added to the atom in going from La to Lu occupy 4f orbitals.
