Classification of Elements and Periodicity

First Element The 1st element on the periodic table is hydrogen that has unique properties. 75% of matter in this universe has this element. Since it is present in all molecules of life, it is said that life cannot exist without hydrogen.  Being part of group 1 in the periodic table, hydrogen shows different characteristics […]

Alkaline earth metals have a first ionisation energy that is defined as the amount of energy required to remove the first electron from a neutral atom. As a result of its smaller radius and the electrons being held tightly by the higher nuclear charge, it is larger than an alkali metal atom. It is also

Isotopes are elements with the same number of protons and electrons but a different number of neutrons. Stable isotopes, primordial isotopes, and radioactive isotopes are the three categories. We’ll learn more about isotopes in this article, including examples, types, and uses, as well as the difference between isobars and isotopes. Isotopes Chemical species with the

The concept that an electron possesses an intrinsic angular momentum that can be identified as a spin was proposed by S.A. Goutsmit and G.E. Uhlenbeck in 1925. Furthermore, the intrinsic angular momentum of each particle is parametrized by spin quantum numbers in atomic physics. The spin quantum number is also the fourth number, with the

Aluminum is a shiny white metal; it is the 13th element in the periodic table. One fantastic reality about aluminum is that it’s the most common and popular metal on earth, making up over 8% of the earth’s centre mass. It’s the third most common chemical component on our planet after oxygen and silicon. It

Despite the fact that people have been utilising the periodic table with phosphorus (P) in it for thousands of years, it was not until 1669 that it was sequestered and given a name by a chemist named Brand that it was officially recognised. Phosphorus is an element that can never be found naturally in our

Every substance is distinct. Each has a distinct color, texture, and appearance, for example. These qualities, while important in determining the identity of a chemical, are frequently insufficient to properly identify it. In general, other physical and chemical properties must be evaluated in order to determine the precise composition of a material. With 92 naturally

The periodic table arranges the elements according to their increasing atomic number. All of these elements exhibit a variety of different trends, and we may utilize the periodic table and the periodic law to comprehend and anticipate the elements’ chemical, physical, and atomic properties. To comprehend the trend, you must first evaluate the electron configuration

Any of the six nonmetallic elements that make up Group 17 (Group VIIa) of the periodic table are referred to as halogen. Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts) are the halogen elements . They were given the name halogen, which comes from the Greek roots hal- (“salt”) and

Lanthanide series and lanthanide contractions are very interesting topics. The behaviour of the outer subshell causes poor shielding and eventually leads to lanthanide contractions. This in turn has consequences on different elements Causes of Lanthanide Contractions The interaction of positive nuclear charge with the outer shell of the orbit, leading to compression of the electrons
