we will learn how to use the periodic table to remember the orbital structure, and then write it using the shorthand notation of electron configurations. Some things to remember:
The electronic configuration of an atom provides information on which orbitals its electrons are in. The Periodic Table below shows how the orbitals occupied by the valence electrons. The number in front of the orbital (1s, 2s, 2p etc) gives the shell (the n quantum number). The letter (s, p, d etc) gives the subshell (the l quantum number).
Electron Configuration Worksheet. This worksheet provides extra practice for writing electron configurations. The easiest and most reliable technique for writing electron configurations is to use the periodic table as your guide.

1. What are the shapes of s, p, and d orbitals respectively? s= spherical p = dumbbell d = cloverleaf. 2. How many 1s orbitals are there in an atom? 4p orbitals? 4d orbitals? 1s: 1 4p: 3 4d: 5. 3. What is the maximum number of orbitals with:
How To write an electron configuration: Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. In another words, atoms are built from the ground upwards.

The sum of the superscripts should equal the total number of electrons.
