8, it goes 2 in the first shell then 8 in all the others until your electron count is up if it ends up with less than a full outer shell then it is looking to combine with another atom who has electrons to spare
The maximum number of electrons that the 5th energy level can hold is 50 electrons. Different atoms can have 1, or 2, or 3, or more electrons in their 5th energy level, up to the maximum of 50 electrons.
The way to work this out is to work out what orbitals are present in the fifth level.
Its all to do with quantum numbers. Each orbital typ s.p,d etc is described by two quantum numbers n (principal) and l (azimuthal). The possible values of l deprnd on the value of n and could be (n-1), (n-2), (n-3) etc.
l= 0 is the s orbital, l=2 is the p orbital, etc.
So for each principal quantum number n there are always n different obital types starting at s.
Level 1 - 1s
Level 2s, 2p
Level 3 3s, 3p, 3d
So for level 5 we can have five types of orbital., s, p, d f, g orbitals
The number of orbitals in each subshell are (and theres an easy pattern to spot here)
s1
p3
d 5
f 7
g 9
So at the fifth energy level we have 25 orbitals which can hold 50 electrons.
For fermium: 30 electrons.
30 electrons
110 electrons
50 since 2(n^2) and n= the energy level
At this level fermium has 30 electrons.
50
The third energy level of an atom can hold eight electrons.
18 electrons
Maximum of 2n2, where n is the energy level.
32 electrons maximum
32 electrons
The fourth energy level can hold up to thirty-two (32) electrons.
The second energy level of atoms can hold a maximum of 8 electrons.
The third energy level of an atom can hold eight electrons.
18 electrons
The first energy level can hold 2. The second level can hold 8. The third level can hold 18. Fourth and beyond can hold 32.
Maximum of 8 electrons in second energy level.
up to 32 electrons
Maximum of 2n2, where n is the energy level.
12
eight!!
There could be a maximum of 8 electrons in the second energy level (n = 2)
32 electrons maximum
