how do you determine how many regions of electron density there are?

You count the number of bonded pairs and lone pairs around the central atom to find the total regions of electron density. Double and triple bonds count as one region of electron density.

In addition to the above reply, remember that a single unpaired electron (found in radicals) counts as a single region of electron density (basically a single unpaired electron is treated as if it were a normal lone pair).

After you draw the lewis structure you can count the number of regions with high electron density which are the bonding pairs and unshared electron pairs around the central atom. Double and triple bonds count as one region of electron density.

The first step is to draw the lewis structure. Electron densities include areas where you are most likely to find electrons. This includes all lone pairs and bonding regions. It's important to note that a double or triple bond would still count as one electron density.

Much Joy,
