Respond to: The outer shell electrons are shown as dots encompassing the image with the atom. These symbols are called Lewis symbols or Lewis constructions.
Due to two lone pairs of electrons on O-atom, repulsion on bond pairs is larger in H20 compared to NH3 . So, the bond angle is significantly less in H20 molecules.
Practice Consistently: Regular practice of chemical equations, stoichiometry problems, and balancing redox reactions should help reinforce your know-how.
Significance: It helps to elucidate why distinctive atoms Mix with one another to variety ionic compounds or covalent compounds.
