P, Cl, and S octet tule exceptions

Postby Aayush Patel 3B » Sun Oct 27, 2019 10:47 am

Why is it that these specific elements have the ability to expand their octet to accommodate more electrons?

These elements are all in the d block, which means they have access to extra orbitals in which they can store electrons.

they're a part of the d block, so they have extra orbitals to hold the electrons

Their n=3 therefore they have access to the d-block (l=2) allowing them to place electrons into the d-block.

Other elements such as N and O and F can't because they are in N=2 meaning they only have access to s and p and can only form an octet. In general just remember n=3 as what makes it an exception.
