carbon forms covalent compounds.justify this statement.
Answers
Answer:
Carbon has 4 electrons in its outermost shell. ... Therefore, carbon completes its octet by sharing its 4 electrons with other carbon atoms or with atoms of other elements and forms covalent bond. It forms strong covalent bonds because of its small size.

Answer:
The atomic number of Carbon is 6 with an electronic configuration of 2,4. Hence, C has 4 electrons in its valence shell. C can lose or gain 4 electrons in order to gain stability. It cannot gain four electron as carbon atom having 6 protons is very small to handle 10 electron and it cannot donate electrons as it needs a lot of energy to do so. Hence, it cannot form C
4+
anion or C
4−
anion and thus forms a covalent bond.
1. Covalent bonds are formed by sharing of electrons. They don't have a free electron that is required for electricity transfer (electricity is the flow of free electrons), thus they are bad conductors.
2. Covalent compounds have low melting and boiling points because they have weak inter-molecular forces between bonds. Hence, less energy/temperature is needed to break the bonds.
