what type of bond is formed between two chlorine atoms?
528587
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms. Hydrogen atoms only need two electrons in their outer level to reach the noble gas structure of helium.

Hydrogen bonds are bonds between a hydrogen in one polar molecule and the negatively charged end of another polar molecule. Hydrogen bonds allow two molecules to link together temporarily. Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.

What kind of chemical bond is CCl4? ... In CCl4 carbon and chlorine is bonded by single covalent bond. Each of them complete their octet by sharing of electron.

Ionic bonds are typically formed between one metallic and one nonmetallic atom. Sodium chloride, or NaCl, is an example of an ionic bond. Another example of an ionic bond is found in lithium fluoride (LiF). Lithium has one electron in its outer shell, and fluorine has seven electrons in its outer shell.

For these bonds the electrons are perfectly equally shared between the two atoms. Polar covalent bonds form between elements with different electronegativities but those that aren't large enough that we could call the bonds ionic. For example the bond between hydrogen and chlorine.

Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

If, however, two isolated fluorine atoms, share electron density, a single covalent bond can be formed in which 2 electrons are localized between 2 electropositive fluorine nuclei; this situation is quite properly described as a covalent bond, and elemental fluorine occurs as the bimolecular gas, F2 .

Chloride ion is the reduced form of chlorine atom. Chloride has 18 electrons compared to seventeen electrons of chlorine, and both have seventeen protons. Therefore, chloride has a negative (-1) charge whereas chlorine is neutral.

Why is an HCl molecule polar while a Cl2 molecule is nonpolar? H & Cl have different electronegativities; therefore they form a polar bond. Cl & Cl have same electronegativity; therefore they form a nonpolar bond.

Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. The electron pair that is bonding HCl together shifts toward the chlorine atom because it has a larger electronegativity value. A bond in which the electron pair is shifted toward one atom is called a polar covalent bond.

BrCl is a polar molecule. It has a linear shape and chlorine has a higher electronegativity than bromine. This results in a polar bond in which the bonding electrons are shifted more towards the Cl atom giving it a partial negative charge and leaving a partial positive charge on the Br atom.

The 3s23p5 electrons are the outermost electrons, so chlorine has seven valence electrons. In a picture, the valence electrons are the ones in the outermost shell.

Due to this ,hydrogen acquires partial positive charge .Development of opposite poles in the molecule due to difference in electronegativity is known as polarity . Thus HCL is a polar molecule so bond between hydrogen and chlorine is Polar covalent.

Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.

Chemical bonding is the process that links elements together to form compounds. KCl is an example of ionic bonding. Below is a simple diagram of potassium and chlorine atoms.

Nitrogen and chlorine have almost identical electronegativities, and so the N-Cl bond is essentially nonpolar. Even so, the one common compound that contains N-Cl bonds, NCl3, is still slightly polar because of the lone pair of electrons on the nitrogen atom.
