Q. Structure of Covalent Bonds?
Ans.
A covalent bond forms between elements that are near each other in the periodic table
While an ionic bond involves an exchange of electrons, a covalent bond involves an overlapping, or sharing, of electrons between the atoms. The overlapping of electron clouds in a hydrogen molecule is shown in the diagram below:
Electron cloud diagrams are rather difficult to draw. A simpler way to show covalent bonding is to sketch electron dot diagrams, using the octet rule.
