how many valence electrons are in fluorine?
16275
Fluorine has 7 valence electrons. Fluorine (represented by F) is an element with atomic number 9, meaning that it has 9 protons in its nucleus,...

A fluorine atom has seven valence electrons. Do you think it is more likely for a fluorine atom to lose seven electrons or gain one electron to obtain an octet?

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.

A: An atom of a group 17 element such as chlorine has seven valence electrons. It is “eager” to gain an extra electron to fill its outer energy level and gain stability. Group 16 elements with six valence electrons are almost as reactive for the same reason.

The number of valence electrons is 7 + 4×7 +1 = 36. If you draw a trial structure in which I is the central atom and every atom has an octet, you will have used 32 electrons. The four extra electrons go onto the central I atom as two lone pairs.

What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.

The number of valence electrons is 5 + 3×7 = 26. If you draw a trial structure in which P is the central atom and every atom has an octet, you will have used 26 electrons. This is the correct number of electrons, so the trial structure is the correct structure.

Fluorine has seven valence electron, just one electron is needed to attain an octet or stable configuration. The implication of the above is that fluorine is very reactive, in fact it is the most reactive non metal, and as a result fluorine is not found in free state in nature.

Boron trifluoride only has six valence electrons and is one of the relatively rare second period covalent molecules that disobeys the octet rule. There are three bonded groups and so no lone pairs. Six electrons implies three electron pairs and therefore a trigonal geometry.

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.

So fluorine has 7 electrons in the outermost shell. Basically, count the number of electrons in the orbitals with the highest principle quantum number, and that'll give the number of electrons in the outermost shell.

The nitrogen trifluoride molecule has 26 valence electrons.

There are a total of 48 valence electrons in the Lewis structure for SF6. Note that Sulfur (S) is in Period 3 on the periodic table and can have an expanded octet and is able to have more than 8 valence electrons.

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.

There are 24 valence electrons available for the Lewis structure for NO3-. It is helpful if you: Try to draw the NO3- Lewis structure before watching the video.

Fluorine has 7 valence electrons, so it will gain one more to fill its octet and have 8.

Lewis Dot of Sulfur Tetrafluoride SF4. S does not follow the octet rule. It will hold more than 8 electrons. Sulfur having valence electrons in the 3rd energy level, will also have access to the 3d sublevel, thus allowing for more than 8 electrons.
