There are 8 electrons in an O shell. The O shell is the second energy level in an atom, and it can hold a maximum of 8 electrons.
The sub-level s of energy that make the o shell is the K-shell.
nothing the shell will grow back
A sea turtles shell stays on its back because its attached
no
Maximum number of electrons = 2n2, where n is the number of shell (n = 1 for K, 2 for L, 3 for M, and so on) K shell has 2 electrons maximum L shell has 8 electrons maximum M shell has 18 electrons maximum N shell has 32 electrons maximum O shell has 50 electrons maximum P shell has 72 electrons maximum
On a turtels back
yes if the shell was a good size and they just wanted to try it.
Shell
No a Turttles shell is it's back and spine.
No. They have a Exoskeleton or shell.
