Science > Mathematics > Algebra > Logarithms > Use of the Laws of Logarithms Set – II In the last article, we have studied to solve problems on the laws of logarithms to evaluate or simplify given logarithmic expression. In this article, we shall study to solve more problems on these laws to prove given […]

Inorganic Chemistry

Silicon

The group IV-A (14) in the periodic table is known as ‘Carbon family’ consist of five elements, namely, Carbon (C), Silicon(Si) Germanium (Ge), Tin (Sn) and Lead (Pb). Carbon is the essential constituent of all organic matter, while silicon is an important constituent of inorganic matter. Electronic Configuration of Group IV(14) Elements: Sr.No. Elements Atomic […]

Physical Chemistry

Atomic Radius

In this article, we shall discuss a very important periodic property called the atomic radius. Atomic Radius: The size of an atom is very small (120 pm). Secondly, since the electron cloud surrounding the atom does not have a sharp boundary, the determination of the atomic size cannot be precise. One practical approach of finding the size of an atom of […]
