http://www.smitaasthana.com/files/f%20block.pdf WebLutetium (Lu) is also sometimes considered to be a d-block element, because it has a complete 4f subshell and a single valence electron in the 5d subshell. Nevertheless, both lanthanum and lutetium are usually included in any general discussion of the lanthanides. The table below lists the lanthanide elements and some of their important properties.
WebJan 30, 2024 · Since the left O has 6 unshared plus 2 shared electrons, it effectively has 7 electrons for a 6-valence-electron O, and thus its formal charge is -1. Formal charge for O = 6 - 6 - (2/2) = -1. Formal charge for S = 6 - 2 - (6/2) = +1. There is yet another structure that does not satisfy the octet rule, but it's a reasonable structure: :.. O..:.. WebCompounds of scandium find use in organic chemistry.
