concept map for chemical bonds
Each atom interacts with another atom by means of a chemical bond such as a covalent bond, hydrogen bond, ionic bond, etc. and forms a new molecule.
If two atoms share electrons, in order to have a completely filled outer shell then the bond formed between the two atoms is called, covalent bond. The covalent bond is the strongest of all the chemical bonds. For example, the formation of a water molecule.
In contrast to a covalent bond, the ionic bond is formed when the atoms are held together by the attraction forces between the oppositely charged ions. An ionic bond is weaker compared to the covalent bond. For example, in sodium chloride, sodium (Na+) and chlorine (Cl) atoms are held together by an ionic bond.
