what is properties of covalent bbond?
Answers
Elements having very high ionisation energies are incapable of transferring electrons and elements having very low electron affinity cannot take up electrons. The atoms of such elements tend to share their electrons with the atoms of other elements or with other atoms of the same element in a way that both the atoms obtain octet configuration in their respective valence shell and thus achieve stability. Such association through sharing of electron pairs among different or same kinds is known as Covalent Bond.
Properties of Covalent Bond
If the normal valence of an atom is not satisfied by sharing a single electron pair between atoms, the atoms may share more than one electron pair between them. Some of the properties of covalent bonds are:
Covalent bonding does not result in the formation of new electrons. The bond only pairs them.
They are very powerful chemical bonds that exist between atoms.
A covalent bond normally contains the energy of about ~80 kilocalories per mole (kcal/mol).
Covalent bonds rarely break spontaneously after it is formed.
Covalent bonds are directional where the atoms that are bonded showcase specific orientations relative to one another.
Most compounds having covalent bonds exhibit relatively low melting points and boiling points.
Compounds with covalent bonds usually have lower
Answer:
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
