Carbon is the central atom. It shares one pair of electron with each of the four chlorine atoms, forming four single bonds.
Each chlorine atom contributes one electron to the bonded pair shared by the two atoms. The remaining six valence electrons of each chlorine atom are not involved in bonding.
By forming four covalent bonds, carbon shares four pairs of electrons, thus filling its outer energy level and achieving stability.
In our textbk “4 pairs of electrons is mentioned”. Shared pair of electrons refer to a bonding pair which is 2 electrons being shared by the 2 atoms (electrons involved in covalent bonding).
How many electrons does carbon atom have?
Under certain bonding conditions, adjacent atoms will form multiple bonds with each other. A double bond is formed when two atoms use two electron pairs to form two covalent bonds; a triple bond results when two atoms share three electron pairs to form three covalent bonds.
In acetylene (C2H2) three pairs of electrons are shared between two atoms of carbon forming a triple bond, while a single pair of electrons is shared between a carbon atom and a hydrogen atom. In this way each hydrogen shell has two electrons, and the second shell of each carbon atom has eight electrons.
Triple covalent bond: The three electron pairs share between the two participating atoms and form a triple covalent bond. It is represented as two dashes [( equiv )].
However, in many molecules atoms attain complete octets by sharing more than one pair of electrons between them: Two electron pairs shared a double bond.
We thus extend our model of valence shell electron pair sharing to conclude that carbon atoms can bond by sharing one, two, or three pairs of electrons as needed to complete an octet of electrons, and that the strength of the bond is greater when more pairs of electrons are shared.
How many bonds can carbon form?
Atoms bond by sharing electrons. In a typical bond two electrons are shared, one from each of the atoms involved. Carbon has four such sharable electrons of its own, so it tends to form four bonds to other atoms.
How many electrons does chlorine have?
The chlorine atom will also have 17 electrons, as an atom is neutral.
How many protons does chlorine have?
While a chlorine atom always has 17 protons, it can have any number of neutrons. Two atoms with the same number of protons and different number of neutrons are called isotopes. Two naturally occurring stable isotopes exist for chloride.
How many shells are there in carbon?
Carbon has two electron shells, with the first holding two electrons and the second holding four out of a possible eight spaces. When atoms bond, they share electrons in their outermost shell. Carbon has four empty spaces in its outer shell, enabling it to bond to four other atoms.
