What are the periodic trends in chemical properties & how to explain

We will discuss the important periodic trends in some fundamental properties such as valency or oxidation state and chemical reactivity. Let’s see how to explain the periodic trends in chemical properties. What is periodicity or periodic trends Periodicity or periodic trend of valence or oxidation state Valency is the number of electrons present in the […]

What is electronegativity and how to apply it

Electronegativity is the tendency to attract the shared pair of electrons towards itself in a covalent bond. Here, in this article we will discuss about electronegativity and how to apply it. What is electronegativity It is the tendency to attract the shared pair of electrons towards itself in a covalent bond. It is represented by […]

What is electron gain enthalpy and how to explain it

Electron gain enthalpy is the energy released when a neutral isolated gaseous atom accepts the electron. Here, we will discuss how the ▲eg H varies in the periodic table. What is electron gain enthalpy It is the amount of energy released when a neutral gaseous atom accepts the extra electron to form anion. X (g) […]

What is ionisation energy and how IE vary in Periodic table

Ionisation energy is the energy required to remove the most loosely bounded valence electron. Here we will also discuss how IE vary in Periodic table. What is ionisation energy The minimum amount of energy required to remove the most loosely bounded electron from the isolated gaseous atom. M (g) + IE ➡️ M+ + e– […]
