I meant to write that chromium was the first element with an electron out of orbital configuration, not argon. I also miss-spelled at least one word - orbitals not 'oebitals'. I should have noted though, that Cu, Ag, Au and roentgenium all lie in one column. And so, show that only the B2 column has all elements in one column out of synchronicity. I'm not making it up. It's just obviously true, write it down, and see if anyone else made note of it,
20 elements do not follow normal s,p,d or f orbitals. In other words, they are out of 'sync'. 4 elements do not have d9 with s2 oebitals filled following in 'symc'. Instead they are s10 d1. That is Cu 3d10 4s1, silver 4d10 5s1, Au 5d10 6s1, and roentgenium 6d10 7s1. Chromium has a chemical formula of (Argon) 5d6 4s1. Argon is the 1st element out of 'sync'. Meaning it does not follow the synchronized pattern of filling the electron orbitals. The other 15 elements out of 'sync' are niobium, molybdenum, ruthenium, rhodium, palladium (4d10, the 5s is completely empty!), lanthanum, cerium, gadolinium, platinum, actinium, thorium, protactinium, uranium, neptunian, and curium. Thorium and palladium have 2 electrons out of 'sync'. Thorium is (radon) 5f empty with 6d2 7s2. Can someone at high speed recite the electron configuration of the spdf orbitals, noting the 20 elements that I just listed as being out of 'symc'. They can also give 7 noble gases, 6 halogens, 6 alkali metals, 6 alkaline earth metals and, the 7 nonmetals. It might be easier if I were to ask if someone could try to make some sort of in sync sense.
