Classification of Elements and Periodicity

We observe light around us in various colours. Did you know that the light we see is a form of energy? Also, what we see around us is not just limited to light. There are various other radiations we cannot notice. They all lie in the electromagnetic spectrum and are known as Electromagnetic Radiation. Electromagnetic […]

The anomalous behaviour of lithium is due to its cation’s small size. Because of its small size and solid nuclear charge, lithium is the most polar alkali metal on negative ions. Thus, lithium-ion has a solid tendency to solvate and form covalent compounds. Li is distinct from other alkali metals because: Dry air melting maintains

There are many different types of allotropes of elements, which are also known as allotropes of elements. Allotropy or allotropism is the property of some chemical elements to exist in two or more different forms, while remaining in the same physical state, which are known as allotropes of elements. As a result, the physical and

The property of chemical elements to exist in numerous different forms in the same physical state is known as allotropism or allotropy. These forms are also called allotropes of elements. Sulphur is a non-metal having atomic mass 40 and atomic number 16, belonging to the chalcogen family of group 16 and period 3 of the

The group 1 elements of the periodic table, except hydrogen, are alkali metals, and the group two elements, except beryllium, are alkaline earth metals. The s-block elements have a typical electronic configuration of ns1 for alkali metals and ns2 for alkaline earth metals.  Because of charge and the addition of an electron to the same

metals, found on the periodic table’s left side in the s-block, are among the most reactive elements on the planet because they quickly shed electrons. Halogens belong to the class of non-metals in group 17. Fluorine, chlorine, bromine, iodine and astatine are halogen elements. These components are too volatile to occur naturally. The electronic configurations

Alkali metals lie in the left row of the periodic table. It contains a total of 6 metals: (Li) lithium, (Na) sodium, (K) potassium, (Rb) rubidium, (Cs) cesium, and (Fr) francium. Alkali metals are also well known as group1 metals as they are of the first group. The group 1 metals are named so because

Actinoids are elements with atomic numbers ranging from 90 to 103, which come after the element Actinium. They include naturally occurring thorium, protactinium, and uranium elements, as well as eleven transuranic elements created artificially through nuclear processes. Despite this, all Actinoids are radioactive.The term “actinide series” comes from the first element in the series, actinium.

Actinides are the group of elements that are the rarest and most radioactive elements in the periodic table. The atomic number lies from 90 to 103, followed by the Actinium. You will find that the elements are prepared artificially. Actinide contraction is the decrease or increase in its atomic number. You can take this article

The abnormal rhythm of the heart means or indicates any variation from the typical sequence of electrical impulses generated in the heart. These variations may cause the electrical impulses too quickly, or too late or irregularly, leading to corresponding changes in the heartbeat rhythm, i.e., they occur either too fast or are delayed or erratic.
