Diffusion is the process wherein the molecules merge as a result of their kinetic energy of random motion. It occurs in liquids and gases because their molecules move randomly. The molecules move from a region of higher concentration to a region of lower concentration, down the concentration gradient, until the concentration equalizes throughout the medium.

When the phenol is taken in excess and the reaction medium is made acidic, the product of the condensation reaction obtained is acidic. Whereas, when the quantity of formaldehyde taken is more than that of phenol in the reacting mixture, and the reaction occurs in a basic medium, the condensation product is known as Resol.
These intermediate condensation products are used as resins in different industries. Bakelite is obtained when Novolac is allowed to undergo cross-linking in the presence of a cross-linking agent. In general, phenol taken in excess acts as the cross-linking agent.

In actinoids, 5f orbitals are filled. These 5f orbitals have a poorer shielding effect than 4f orbitals (in lanthanoids). Thus, the effective nuclear charge experienced by electrons in valence shells in case of actinoids is much more that than experienced by lanthanoids. Hence, the size contraction in actinoids is greater as compared to that in lanthanoids.

Interhalogen Compounds are the subordinates of halogens. Compounds containing two unique sorts of halogens are termed as interhalogen compounds.
Example: Chlorine monofluoride, bromine trifluoride, iodine pentafluoride, iodine heptafluoride, etc.

Nitrogen is chemically less reactive. This is because of the high stability of its molecule, N2. In N2, the two nitrogen atoms form a triple bond. This triple bond has very high bond strength, which is very difficult to break. It is because of nitrogen's small size that it is able to form pπ-pπ bonds with itself. This property is not exhibited by atoms such as phosphorus. Thus, phosphorus is more reactive than nitrogen.
