Classification of Elements and Periodicity

Natural elements are those elements that are freely available in nature and are therefore referred to as such. There are 118 elements in the periodic table, and all of the elements (118) do not occur naturally in nature. With the exception of Technetium (43) and promethium, the naturally occurring elements are 1-92. (61). Consequently, the […]

The physical and chemical properties of elements are nothing but the periodic functions of the atomic numbers, according to the modern periodic law. Across each row, scientists placed elements in increasing order of their atomic numbers from left to right. And it was discovered that elements with comparable qualities recur at regular intervals. Why atomic

The elements of the periodic table can be divided into two kinds, which are often referred to as metals and non-metals, according to their chemical properties. Each of these elements has a unique set of features and can be found in a variety of settings, including buildings, bridges, roads, electric wires, automobiles, laptop computers, and

Minerals are found everywhere, from the rock salt we use to cook with, to the Kohinoor diamond set on the crown of the Queen of England!! On Earth, more than 4000 different types of naturally occurring minerals have been discovered. Metals, precious stones such as rubies, sapphires, and diamonds, and a variety of other valuable

What are Lanthanides Elements? Lanthanides (Rare earth elements )  made up the modern periodic table, which includes elements with atomic numbers ranging from 58 to 71 after Lanthanum. Rare earth metals are so named because they only make up a small percentage of the Earth’s crust (3% percent). As lanthanide orthophosphates, they can be found in

Introduction  Isotropy Materials, such as glass, have the same characteristics in all directions as graphite. As a result, we may classify materials based on their isotropy. Isotropy is derived from the Greek words isos (equal) and tropos (uniform) and means “uniform in all directions” (way). Anisotropic materials, such as graphite, have varying material properties depending

To put it another way, the word isotope is derived from two Greek words: isos and topos, which both mean “the same place.” Therefore, the concept behind using the term “isotopes” is that different isotopes of a single element can be found in the same position on the periodic table. Isotope The term “isotope” refers

Elements have standard atomic numbers, but different molecular masses are isotopes. An isotope of an element possesses almost similar chemical properties as other elements or other isotopes of that particular element. Isotopes have the same no. of protons in their outer shell. They differ by the number of neutrons present in their nuclei. Understanding the

Isomers are chemical compounds which has the identical chemical formulas but different in the characteristics and atomic arrangement in the molecule, as a result, the substances that displays isomerism are known as isomers. “Isomer” comes from the Greek words “isos” and “meros,” which both imply “equal pieces.” In the year 1830, the Swedish chemist Jacob
