The image depicts three chemical structures: 1. **On the left**: - The structure is of a six-membered ring with a positive charge. - There is a nitrogen atom attached to the ring with two methyl groups. - A double bond and a positive charge are present in the ring, indicating a pyridinium ion. 2. **In the center**: - The structure shows a six-membered ring with a positive charge. - An oxygen atom bonded to a methyl group is attached to the ring. - A double bond is present in the ring, indicative of a methoxy-substituted pyridinium ion. 3. **On the right**: - The structure consists of a bicyclic system with nitrogen and a ketone group. - The first ring is a six-membered aromatic ring with a nitrogen atom (pyridine-like structure). - The second ring is a six-membered ring containing a ketone group, forming a quinolone structure. These structures represent different types of heterocyclic compounds often found in various chemical and pharmaceutical applications.

Actinides

The elements in which the extra electron tends to enter the 5f-orbitals of (n–2)th main shell are considered 5f-block elements. They are also named actinides. Actinides include 15 elements, from atomic number 89 to 103.
