I know they're located in the quot;outermost shellquot; of the atom, but principal energy levels are synonomous to shellsDoes that mean they are located in the principal energy levels (n1, n2, etc)? But the first 7 principal energy levels contain 2, 8, 18, 32, 50, 72 and 98 electrons, respectively and elements can only have a maximum of 8 valence electrons, so that can't be the caseEach orbital may contain a maximum of 2 electrons so they can't be there eitherI am just having trouble visualizing where the valence electrons are within the atomHelp!?!?
Does that imply they're located in the primary power stages? yes elements can most effective have a highest of 8 valence electrons, so that are not able to be the casenonetheless, it'sThe n 1 level can most effective keep 2 electrons (s subshell), so there are most effective two factors on the primary row of the periodic table: Hydrogen and HeliumHe has a full outer shell with 2 electronsThe n 2 stage can maintain as much as eight electrons (s and p subshells)There are 8 elements on row 2 of the periodic table, and the inert element Neon has 8 electrons in its full n 2 levelYour confusion traditionally starts at the n three stageIt has an s, p and d subshell retaining 2, 6 and 10 for a complete of 18 electrons altogetherSure that shell is indeed full with eight electrons, when the s and p subshells are fullThat aspect is ArgonYet there may be nonetheless a 3d shellWhile you get to the core of the periodic desk, you start filling that upRow four of the periodic table starts by way of filling up the 4s shellHowever then opening with Sc (aspect 21), you begin filling up 3d while you could have only 2 electrons in the 4sAt Zn (detail 30) the 3d shell is full, the n 3 shell is full, and then you definately begin filling up the 6 electrons in the 4p shellThere's nonetheless a 4d shell, however you don't start filling that until the center of the n 5 rowAnd there's a 4f shell which is being crammed from factors 57-70 which is after the commencing of the n 6 rowAt this factor my reminiscence of chemistry category breaks downI know this order has to with vigour, that 3d is larger vigour than 4s, and that 4d is better power than 5s, and that's why it fills afterI don't take into account why an aspect with 4s and 4p is inert though, although there's a 4d levelIt additionally has to do with vigour I suppose.
