WebIf helium is in group 8 why does it not have 8 valence electrons . And when two hydrogen atoms combine they make a molecule and then have a total of 2 valence electrons if they are then stable then why are the elements in group 2 not stable with 2 valence electrons ? • ( 13 votes) Upvote Flag Just Keith 8 years ago WebThe K shell contains a 1s subshell hence it can carry 2 electrons, the L shell has 2s and 2p, and can carry 8 electrons. The M shell contains 3s, 3p, and 3d, and can carry 18 electrons. The N shell containing 4s, 4d, 4p and 4f, …

(CC SA-BY 4.0; Derrekli) There is no overall charge on the molecule and there is one anionic ligand (CH 3- ) The Re metal must have a positive charge that balances out the anionic ligand charge to equal the 0 overall molecular charge. Web30 sep. 2024 · Updated on September 30, 2024. The words valence and valency have two related meanings in chemistry. Valence describes how easily an atom or radical can combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. Valence is denoted … WebThe complete electron configuration of cobalt is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^7. This configuration includes the argon core ( [Ar]:1s^2 2s^2 2p^6 3s^2 3p^6). These electrons are core electrons because they are stable and do not take part in bonding. The remaining electrons are called valence because they do take part in bonding. installing ceramic tile shower stall
