Carbon atoms can only make a maximum of 4 bonds, since it contains only 4 electrons in its coverings. The bonds that carbon atom can make are the following: one double and one single bonds. two double bonds.

Yes, there are coordination complexes of large elements which have coordination numbers greater than eight. Some examples are: [ReH9]2− with a tricapped trigonal prismatic structure. The nine hydride ligands are small enough to fit around the relatively large rhenium atom fairly easily.

A stable arrangement is attended when the atom is surrounded by eight electrons. This octet can be made up by own electrons and some electrons which are shared. Thus, an atom continues to form bonds until an octet of electrons is made.

A double covalent bond is where two pairs of electrons are shared between the atoms rather than just one pair. Two oxygen atoms can both achieve stable structures by sharing two pairs of electrons as in the diagram. The double bond is shown conventionally by two lines joining the atoms.

Two chlorine atoms can share 1 electron each to form a single covalent bond. They become a Cl2 molecule. Two oxygen atoms must share 2 electrons each to complete each other’s shells, making a total of 4 shared electrons. Because twice as many electrons are shared, this is called a ‘double covalent bond’.

Double bonds are shorter than single bonds because double bonds are stronger and therefore pull the electrons closer together in the two elements which decreases the length of the bond.

A covalent bond also occurs in Cl2. In the chlorine molecule, the two chlorine atoms are attracted to the same pair of electrons. Each chlorine atom has seven valence electrons in the third energy level and requires one more electron to form an electron core with an argon electron configuration.

In reality there is no difference between them. 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.

Chlorine is a simple molecule. each chlorine atom can count 8 electrons in its outer shell. One pair of shared electrons form a single covalent bond.

Answer: Chlorine does not make double bonds. Oxygen needs two bonds (two single bonds or one double bond) and two lone pairs to complete its octet. Chlorine will only make single bonds unless for example it is bonded to oxygen (ClO3H), then it has to have double bonds because of the oxygen.

A chlorine atom can form a single covalent bond, according to the University of Wisconsin chemistry department website. Chlorine atoms have seven electrons in their outer shells and can only share a single electron with another atom to fill that outer electron shell.

5 bonds

There are SEVEN bonds to the chlorine centre, each of which is composed of 2 electrons, and the chlorine “OWNS” seven of the 14 electrons … iodine is thus FORMALLY neutral…
