How many electrons are in a shell?

Answer 1

The number of electrons in a shell varys depending on its location. The outer shell is usually paid the most attention to(the valence shell), and a stable outer shell (when considering a noble gas) bust have 8 electrons (with the exception of He). If there is less than 8 electrons, this is considered to be unstable, and makes it easier to lose electrons to other atoms.

Answer 2

I depends on the shell. S-shell has only two electrons if all levels are occupied. P-shell has 6 electrons for the same condition and so on. This also depends on how much mass or matter there is in each shell!!!

Answer 3

First shell = 2 electrons

Third shell = 8 electrons

Fourth shell = 18 electrons

Fifth shell = 18 electrons

Sixth shell = 32 electrons

Seventh shell = 32 electrons

(Used by calculating differences in atomic numbers of Noble Gases)

Answer 4

1. 2
2. 8 =2+6
3. 18=8+10
4. 32=18+14
5. 50=32+18
6. 72=50+22
7. 98=72+26

Answer 5

2, 8, 8, 18, 32
