Aufbau principle - -procedure in which the electron configuration of the elements is determined by "building" them in order of atomic numbers, adding one proton to the nucleus and one electron to the proper subshell at a time core electron - -electron in an atom that occupies the orbitals of the inner shells electron configuration - -electronic structure of an atom in its ground state given as a listing of the orbitals occupied by the electrons Hund's rule - -Every orbital in a subshell...

What consists of a small, positively charged nucleus surrounded by electrons? an atom What does a nucleus consist of? protons and neutrons Atomic number? the number of protons in the nucleus Mass number? the total number of protons and neutrons in the nucleus Isotopes? atoms of the same element that have the same atomic number (protons) but different mass numbers (neutrons) How to find average atomic mass? natural % abundance x mass (amu),of each isotope,...

How many electrons can each orbital hold? Two How many electrons can be held in each sub shell? S - 2 P - 6 D - 10 F - 18 Put the sub shells in order do their energy, lowest to highest S, p, d and f How do we fill the p and d subshells singly first and then doubly What is an orbital? A region of space around the nucleus where there is a 95% chances of finding an electron What is the Aufbau principle? An electron occupies the lowest-energy orbital tha...
