Beryllium, or Be, has two electrons in both the first and second shell. The atomic number is 4 if you need to find it on the Periodic Table.
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
inner-shell electrons
The highest energy shell of Fluorine is 2nd shell which contains 7 electrons just like other halogens.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
inner shell electrons : the electrons that are not in the the highest occupied energy level .
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )

electrons
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
The element with 4 valence electrons in the 6th shell is lead (Pb). Lead has 4 electrons in its outermost shell, which is the 6th electron shell.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
amount of electrons in their outermost shell that their shell can hold in relative of one to maximum amount their outer shell can handle in a stable element.
They both show the amount of electrons in the outer shell.
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
If the number of electrons in the M shell is equal to the sum of the electrons in the K and L shells, then the element is Silicon (atomic number 14). It has 4 electrons in the K shell, 8 in the L shell, and 2 in the M shell.
