Which electrons are the valence electrons in a neutral atom of fluorine (F)? Write the orbital configuration of just the valence
ICE Princess25 [194]

Answer:

2s² 2p⁵

There are seven valance electrons in fluorine.

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other.

Properties of fluorine:

1. it is yellow in color.

2. it is flammable gas.

3. it is highly corrosive.

4. fluorine has pungent smell.

5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.  

Electronic configuration of fluorine:

F₉ = 1s² 2s² 2p⁵

Valance electrons in fluorine are 2s² 2p⁵.

Valance Orbital configuration:

2s² 2p⁵

There are seven valance electrons in fluorine.

Chemical bonds form because: a. The atoms have more energy bonded together than separated b. The atoms have less energy bonded t
MrMuchimi

Answer:

A. The atoms have more energy together than separated.

Explanation:

There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons  pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.

Atoms with lower forces typically don't typically bond with other atoms of lower forces.
