how many ELECTRONS ARE UNPAIRED IN THE OUTERMOST SHELL OF ALUMINUM (Al, ATOMIC NUMBER 13)?
the respond is b) 3the 1st electron shell can basically carry 2 electrons: 2e) the 2nd shell can basically carry 8so if akuminum has 13 electrons: 2e) 8e) because of the fact the 1st shell holds 2 and 11 greater electrons are needed to get a finished of 13 electrons you should function greater shellsthe 2nd shell can basically postpone to eight however so which you like one greater shell to incorporate the extra 3 electrons: 2e) 8e) 3e) because of the fact the shell protecting 3 electrons is the outer shell, above the different shell(s) then 7 electrons are got here upon in the outermost shell of this factor.
