New Classification Model for Chemical Elements Based on the Characteristic Graph of the Atom | Chapter 8 | Chemical and Materials Sciences: Developments and Innovations Vol. 6

The classification of chemical elements has long been a major challenge and a rich source of knowledge in chemistry. After several attempts, the current classification has been accepted by the scientific world. The periodic table is one of the most profound and unifying concepts in modern science. However, beyond Mendeleev’s famous table, there have been several models for this classification: the spiral model, the tabulated model, Pierre Demers' pyramid model, etc. This chapter explores a new classification model based on the characteristic graph of the atom presented in previous publications. It elucidates the periodic and ordered classifications of the elements. Three types of classification emerge from the graph: periodic, ordered and hybrid. The hybrid classification resembles the periodic table, but incorporates elements from the ordered form. In this model, all the normal elements are arranged on the right and the transition elements on the left. In addition, new methods of illustration, such as condensed ‘order’ and ‘period’ tables, were introduced. These results reveal that the classification extends beyond periodicity, encompassing an ordered classification of chemical elements. This research sheds light on the various approaches to the classification of elements and opens the way to new explorations in the field of chemistry.

Biomedical Applications of Some Schiff Base Metal Complexes Containing Imidazole/Thiophene Derivatives | Chapter 5 | Current Advances in Chemistry and Biochemistry Vol. 9

 Schiff base was produced by condensing imidazole-2-carboxaldehyde with 2-amino-3-carboxyethyl-4,5-dimethyl thiophene in a 1:1 molar ratio. Schiff base complexes of CoII, NiII, CuII, and ZnII were produced and studied. Magnetic and electronic spectrum data were used to propose the complexes' shape. The thermal stability of the compounds was determined using thermal analysis. The fluorescence spectral study of the Schiff base and its CuII complex in various solvents was examined. The grain size was determined using powder XRD measurements. The surface morphology of the complexes is depicted in SEM pictures. The antibacterial and antifungal activity were tested using Kirby-disk Bauer's diffusion method. MTT assay was used to conduct in vitro anticancer investigations on a human cervical carcinoma cell line.
