CHE 101 Unit VI: Atomic Structure & Periodic Props. Page 171 Which of the following orbital designations are not possible? Explain List the element which fits each of the following descriptions: a) The lightest atom containing a half-filled p subshell b) The lightest atom containing a half-filled d subshell c) The heaviest noble gas that has no electrons in d orbitals d) Two elements with two unpaired 2p electrons An element whose dipositive cation has the same electronic configuration (isoelectronic) as Ne. f) An element whose negative one ion is isoelectronic with Ne. How many unpaired electrons can be found in the following in their ground states?

Answer 1

анц. For a given value of ne principal possible values of e are n-1, quantum numbers, the -2, and so on.. i uf n=4 Possible value of l = 3, 2, 1, i 4f orbital is possible in 10 mel, l=1 Not possible wi) 60 n=6, 6=2 Possible. cuin as d=0 n=a, possible in zd n=2, l = 2 not possible (v) 36 n=3 l=3 Not possible
