Difficulty: how to deal accurately with both the core and valence electronsJ. Bernholc
we observe that the 21st electron occupies the 3d sub-shell. However, as the previously filled 4th shell (4s) has 2 electrons and is apparently the outermost shell, the number of valence electrons is 2.
According to the octet rule, how many electrons must be located within this valance shell in order for it to stop forming bonds and become inert? How many valence electrons does the element with atomic number 117 have, and w...
