Also, we have to make sure that the electron configuration will match the order of aufbau principle (i.e., the 1s subshell is filled first and then 2s, 2p, 3s and so on). electron configuration, Hunds rule, orbital, Pauli exclusion principle, period, shell, spin, subshell, Elvis Perkins, a rather shy fellow, is getting on the bus shown at right. The first two electrons of argon enter the 1s orbital. each orbit can hold an unlimited number of electrons. The electrons in an atom fill up its atomic orbitals according to the Aufbau Principle; "Aufbau," in German, means "building up." The Aufbau Principle, which incorporates the Pauli Exclusion Principle and Hund's Rule prescribes a few simple rules to determine the order in which electrons fill atomic orbitals: The little superscript represents the number of electrons in each number/letter combination.

Argon has 8 valence electrons in its outermost shell. : Create the correct electron configuration for argon. This means that the argon atom has two electrons in the first energy level, two electrons in the second energy level, six electrons in the third energy level, and so on. Why do you think this section is ten columns wide? Again, we have used 2 electrons in the 2s subshell, so we have a total of 16 2 = 14 electrons left. For example, 1s is lower energy than 2s, which in turn is lower energy than 2p. A chemist would shorten this notation to just 3d7 calling Copper by the subshell of highest energy that contains any electrons. An abbreviated method for electron configurations uses a set of square brackets [ ] around the chemical symbol of the noble gas.
