Write any two neccessory conditions for the formation of covalent bond
Answers
Answer:
Some of important conditions for formation of covalent bonds are :
(i) Both atoms should have four or more electrons in their outermost shells, i.e., non-metals.
(ii) Both the atoms should have high electronegativity.
(iii) Both the atoms should have high electron affinity and high ionization potential.
(iv) Electronegativity difference between the two atoms should be zero or negligible.
(v) Thee approach of the atoms towards one another should be accompanied by decrease of energy.
Answer:
Explanation:
A covalent bond is formed between two non-metals. The difference in electronegativity between the combining atoms of the two non-metals must be sufficiently low. The two combining atoms should have high ionization energy. The two combining atoms should have high electron affinity
