isn't it just one full shell of two electrons?
OpenStudy (lgbasallote):
yeah..im just making sure...so Hydrogen is the only one that goes by 1s^1? since the later elements all start with 1s^2 right?
OpenStudy (anonymous):
yep... then you can use the formula 2(x)^2 where x is the shell number ... the answer you get is the number of electrons in that shell.
OpenStudy (lgbasallote):
