Electronic configuration is the arrangement of electrons in the atomic orbital. Here, are the rules to write the configuration of electron in the atomic orbital. Rules for filling electronic configuration in an atomic orbital There are some rules to fill the electronic configuration in an element. Let’s discuss them one by one : Aufbau Principle […]

Stoichiometry calculations gives the relationship between reactants and products. Here, we will discuss about the calculations in terms of moles, masses and volumes. What is Stoichiometry coefficients The coefficients of the balanced chemical equation is called stoichiometric coefficients. For example : CaCO3 + 2HCl ➡️ CaCl2 + H2O + CO2 1 mole 2 moles 1 […]

Avogadro’s number helps in many numerical calculations. Here, we will discuss the important relationships in the mole concept. Avogadro’s number may be defined as the number of atoms present in one gram atom of the element. It is also equal to the number of molecules present in one gram molecule of the substance. 1 mole […]

Firstly, we will understand about the term solutions. Afterwards, we will discuss the ways of expressing concentration of solutions. Expressing the concentration of the solutions A solution is a homogeneous mixture of two or more chemically non reacting solute and solvent components. Solute is the component which is present in lesser amount in the solution. […]
