So... for the element of FLUORINE, you already know that the atomic number tells you the number of electrons. That means there are 9 electrons in a fluorine atom. Looking at the picture, you can see there are two electrons in shell one and seven in shell two.

Hydrogen has 1 electron in the first shell (so one valence electron). Helium has 2 electrons --- both in the first shell (so two valence electrons).

Since they are in the same Group on the periodic table they each have the same number of electrons (7). For the CF2Cl2 Lewis structure there are a total of 32 valence electrons available.

Fluorine, F It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F -. Note that the atom is called fluorine, but the ion is called fluoride. A fluoride ion has the same electronic structure as a neon atom (Ne).

How many more electrons can fit in the valence shell of a fluorine atom? 1 more elctron can fit, to make the number of valence electrons to 8.

Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.

In an atom, the electrons spin around the center, also called the nucleus. The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons.

The fourth shell has 4 subshells: the s subshell, which has 1 orbital with 2 electrons, the p subshell, which has 3 orbitals with 6 electrons, the d subshell, which has 5 orbitals with 10 electrons, and the f subshell, which has 7 orbitals with 14 electrons, for a total of 16 orbitals and 32 electrons.

Every element in the first column (group one) has one electron in its outer shell. Every element in the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell.

Fluorine has seven valence electrons and usually forms the F – ion because it gains one electron to satisfy the octet rule.

Similarly, L shell is the second shell and it can hold up to 2(2)2 = 8 electrons. This formula helps to calculate the maximum number of electrons that an orbit can accommodate.

The L shell only holds eight electrons. The M shell only holds eight electrons. The M shell can actually hold up to 18 electrons as you move to higher atomic numbers. The maximum number of electrons you will find in any shell is 32.

Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital.
