Explain giving reason why carbon neither forms c positive cations and c
negative anions but forms covalent compounds which are bad conductor of electricity and have low melting and boiling point
Answers
Carbon is only one element that can form covalent bond means C-C bond because of its unique atomic number.
It's nuclear charge on its outermost
electron is such that it can't lose electron or gain it hence it shares outermost electron to form covalent bond. Atomic radius is also a factor that affects on it.
♤ Carbon can't lose 4 electron to form C^4+ ions as very high energy is required to remove 4 electrons.
♤ Carbon can not gain 4 electron to form C^4- ions as 6 protons can not hold 10 ♤ electrons and Energy needs to be supplied to overcome repulsion.
♤ Carbon can share 4 electron to form covalent compounds.
♤ Carbons do not conduct electricity as they are non - polar and do not form ions.
♤ They have low melting points and boiling points due to weak van der Waal's force of attraction between molecules
