Elements in different blocks and forming an octate

Postby Connie Liang 3L » Wed Nov 11, 2020 3:37 pm

In lectures, Dr. Lavelle mentions that elements in the p-block especially want to form an octate. I understand this is because the s orbitals allow for two electrons and the p-block allows for 6 electrons for a total of 8. However, do elements in the d-block want to form octates as well or is it only elements in the p-block?

I think d-block elements want to fill their electron shells as well, and I read somewhere about the "18-electron rule" for d-block elements because they also need 10 electrons in their d shell. Octet refers only to the s2p6 configuration, which does not take electrons in the d orbital into account

I would think that as the person said above, that they want to fill out all their orbitals up. I think this can explain as to why elements in period 3 can have expanded octets because they would not mind filling up their orbitals as I believe thats the main goal.
