Atoms tend to form ions or chemical bonds in order to end up with filled outer "s" and "p" subshells. This is called the "octet" rule. (Not all chemical bonds follow this - it's a RULE OF THUMB, not a scientific law!) 162. E N E R G Y 1s 2s 2p 3s 3p 3d 4s 4p 4d 5s 5p Example: Oxygen, Z = 8 Valence electrons for oxygen.

Electron Configuration Electron configurations are the summary of where the electrons are around a nucleus. As we learned earlier, each neutral atom has a number of electrons equal to its number of protons.

We need electron configurations so that we can determine the number of electrons in the outermost energy level. These are called valence electrons . The number of valence electrons determines how many and what this atom (or ion) can bond to in order to make a molecule 1s22s22p63s23p64s23d104p65s24d105p66s24f14É etc.

We know the electron configuration and that all the orbital sets are full (all electrons paired) through 4d. It is the 5p level that is partially full. Only 3 electrons go into the set - so all three go in as single UNpaired electrons with parallel spin states (all +½ or ↿). Specifically... 5p = ↿ ↿ ↿
