how many electrons has fluorine atom?
188643
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.

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?

Beryllium Fluoride Two fluorine (F) atoms can also bond with one beryllium (Be) atom, making the formula BeF2. Beryllium gives up one of it's electrons to each of the fluorine atoms. The result give each of the fluorines eight electrons, making their shells full.

What is the structure of phosphorus pentafluoride? Bond the 5 F to a central P, and complete the octets on the surrounding atoms. This uses all 40 electrons, and P, the central atom, has a share in 10 valence electrons.

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

1) They all have 7 valent electrons. 2)They are highly electronegative chemicals and readily form “halides” with hydrogen. This is why Fluorine one of the most reactive chemicals on the planet. 3) Because of they are just one electron away from a complete octet, they tend to exist freely as gases.

11.2 L of fluorine (F2 molecules) contains 0.500 mol of F2 molecules at STP. 22.4 L of neon contains 6.02 × 1023 atoms of Ne at STP. Therefore volume = 2.00 mol × 22.4 L mol–1 = 44.8 L.

Fluorine, F It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F -.

The first energy level has 2 electrons located in the 1s-orbital and the second energy level, which in fluorine's case is the outermost energy level, has 7 electrons, 2 in the 2s-orbital and 5 in the 2p-orbitals. This means that fluorine has a total of 7 valence electrons.

Group 17 elements, including fluorine and chlorine, have seven electrons in their outmost shells, so they tend to fill this shell with an electron from other atoms or molecules, making them negatively charged ions.

Fluorine is highly electronegative. Therefore, fluorine atom has strong tendency to attract the electrons. has two manganese atoms and seven oxygen atoms so oxygen atom does not create crowd surrounding the manganese atoms. Hence MnF7 is not stable but Mn2O7 is stable.

Covalently sharing two electrons is also known as a “single bond.” Carbon will have to form four single bonds with four different fluorine atoms to fill its octet. The result is CF4 or carbon tetrafluoride.

Example 1: A fluorine atom can get a full valence shell by either gaining one more electron, or by losing seven electrons. The former requires the transfer of less electrons, so the fluorine atom will try to gain one electron first. Therefore, F− ions are more common than F7+ ions.

Sulfur hexafluorideIn the SF6 molecule, the central sulfur atom is bonded to six fluorine atoms, so sulfur has 12 bonding electrons around it. The overall geometry of the molecule is depicted (tetragonal bipyramidal, or octahedral), and bond angles and lengths are highlighted.

So fluorine has 7 electrons in the outermost shell.

Type of Bonding: This compound consists of 6 atoms of fluorine attached to a central atom of sulfur. ... The structure has a Sulfur atom in the middle with 6 Fluorine atoms surrounding this structure. Each fluorine atom has 3 unshared pairs to achieve the octet rule. In addition, this bond is polar covalent.
