2 in the first shell- made up of one S sub shell(containing 2 electrons),

8 in the second shell- made up of an S sub shell(containing 2 electrons) and a P sub shell(containing 6 electrons),

18 in the third shell- made up of an S sub shell (containing 2 electrons) a P sub shell(containing 6 electrons) and a D sub shell(containing 10 electrons),

36 in the fourth shell- made up of an S sub shell(containing 2 electrons) a P sub shell(containing 6 electrons) a D sub shell(containing 10 electrons) and an F sub shell(containing 18 electrons),

36 in the fifth shell- made up of an S sub shell(containing 2 electrons) a P sub shell(containing 6 electrons) a D sub shell(containing 10 electrons) and an F sub shell(containing 18 electrons),

18 in the sixth shell- made up of an S sub shell(containing 2 electrons) a P sub shell(containing 6 electrons) and a D sub shell(containing 10 electrons),

hope that helps x

Hey, Im assuming that because you're asking this question you're studying chemistry at high school or GCSE level. If so then all you really need to know is that 2 electrons can fit into the first shell, and then 8 into each shell after that.
To be more advanced you would be looking at electronic configurations, where you would have subshells called (in order from inner shells to outer), 1s 2s 2p 3s 3p 4s 3d 4p........

The 's', 'p' and 'd' labels are just names for the different types of shell, or orbital. S orbitals can hold 2 electrons, P orbitals can hold 6 and D orbitals can hold 10. The orbitals build up in the order stated above, so an element with 3 electrons (Lithium) would have 2 electrons in the 1s shell and the other 1 electron would be in the 2s shell.
I hope this doesnt sound too complitcated, like I said, the second explaination is the more advanced one, its most likely that you only need the first one for now. Hope this helps.

The maximum number that can fit into any ring or shell is given by the formula 2n^2.
1st = 2
2nd= 8
3rd = 18
4th = 32
5th = 50
6th = 72
7th = 98
Note that if it is an outer shell or ring then the maximum number in that outermost one is 8 with the exception of the first shell which can only hold 2 electrons.

first ring can have 2 then all others will have 8 ....not more

Right now i am studying basic chem so wat i have learnt is that first ring can hold maximum 2 electrons and rest maximum is 8 electrons.

ok based on my high school knowledge I'm going to say
2
8
8
8
8
8
8

like I said, "high school" knowledge, I've been told it's really much more complicated
