im learning this in science, the most direct answer is 8, the equation to figure this out is 2 times n times n where n is the energy level in this case, 2, so 2 times 2 times 2=8. but once you get to the 18th element (i believe it is potassium) and above this equation no longer applies, but the most number of electrons possible on the second shell is still 8, no matter what element
There are eight electrons in a full second shell. (Two electrons in a full first shell.)
The number of electrons that can go into any given principal quantum number (shell) n is 2n2. So there are 8 electrons in the second shell, and 18 in the third.
Of what element
8 electrons
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
4 electrons
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
Eight electrons fit in the second shell.
lose 3 electrons from its second shell
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
8 electrons
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
4 electrons
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
it takes 8 electrons for the second shell to be considered full
Eight electrons fit in the second shell.
There 8 electrons in the second shell.
4
Second shell has a maximum of 8 electrons.
lose 3 electrons from its second shell
The second shell can hold eight electrons.
