Expanded Valence Shells

Postby Ryan Chang 1C » Sat Nov 02, 2019 2:23 pm

Up to how many electrons can be held in the valence shell of capable elements?

8 valence electrons is the limit for an element to hold in a given shell. If there are more than 8, then a new shell is formed.

The standard is 8 valence e- in the outer orbital but after the 3rd period, the elements have access to the d-orbital which means they can have more than 8 valence e- in the outer orbital.

Is this why some elements end up breaking the octet rule?

Yeah, elements in period 3 or higher don't have to abide by the octet rule.
