Modern periodic table, periodic properties

In the present day, we use different metals but at starting means in ancient times (Stone Age) first known metals are silver, copper, and gold. This occurred in the metallic or native state in form of sand and gravels of riverbeds.  Elements are found to occur in nature either in the Free State (also called […]

Classification of Elements Everything, from the air we breathe to the food we eat, is made up of numerous components that serve as the basic building blocks. Pick up anything in your environment and you’ll be shocked at the composition of its stuff. Deep research into the matter around us uncovers numerous unique and fascinating

The chemical element germanium has the symbol Ge and the atomic number 32. Pure germanium is a semiconductor that resembles elemental silicon in appearance. In nature, germanium, like silicon, interacts with oxygen and creates complexes. Germanium was discovered relatively late in the history of chemistry due to the fact that it is rarely found in

The key difference between group 1 and group 2 components is that everyone group 1 components have unpaired electrons in their outermost orbital, whereas group 2 components have paired electrons in their outermost orbital. S block components are found in groups 1 and 2 of the periodic table. That means; these parts have their outermost

As we know there are many chemical elements present on our planet. The periodic table is a way by which all the chemical elements are represented in a tabular form. This periodic table is in different aspects and branches of science such as physics, chemistry, etc. As there are many chemical elements in the plant

On the periodic table, the elements Fluorine, Chlorine, Bromine, Iodine, Astatine, and Tennessine together form a group known as Group 17. These elements are not metals (non-metals) but are highly reactive and somewhat similar in terms of their properties, which are not found in other groups of elements on the periodic table. Each of these

The alkali metals are in group I, the alkaline earth metals are in group II, the pnictogens are in group 16, the chalcogens are in group 17, the halogens are in group 18, and the noble gases are in group 18. Group I elements –  The alkali metals are made up of the chemical elements

The groups IA and IIA are placed at the extreme left corner of the periodic table. The elements of these two groups belong to the S block as the differentiating electron enters the S orbital in all these elements. As the S-orbital can accommodate only two electrons, these two groups (IA & IIA) belong to

So, how do these mathematically defined orbitals tie in with the electron shells we observed in the Bohr model? We can split each electron shell down into one or more subshells, which are just sets of one or more orbitals. Subshells are identified by the letters s, p, d, and f, and each letter implies

Periodic trends are unique patterns in chemical element properties revealed by the periodic table of elements. Electronegativity, ionisation energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity are all major periodic patterns. Periodic trends are caused by changes in chemical elements’ atomic structure within their respective periods and groups (horizontal rows and
