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 […]
What is Heisenberg’s Uncertainty Principle in atomic structure
Heisenberg’s Uncertainty Principle is applicable for the microscopic particles only. Let’s discuss about the Uncertainty Principle in detail. What is Heisenberg’s Uncertainty Principle It is impossible to measure simultaneously the position and momentum of a small microscopic particle with absolute accuracy. if one of them is measured with absolute accuracy, the other becomes less accurate. […]
What is Rutherford’s scattering experiment in atomic structure
Rutherford scattering experiment involves the bombardment of thin foils with alpha particles. This results in the discovery of nucleus. Here, we will discuss about Rutherfords scattering experiment in structure of atom. What is Rutherford’s scattering experiment What are the observations of Rutherford’s scattering experiment What are the conclusions of Rutherford’s scattering experiment Structure of Rutherford’s […]
How to do Stoichiometry calculations in basic concepts of Chemistry
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 […]
How to find the empirical formula and molecular formula
Empirical formula is the simplest whole number ratio of various elements in the compound. Molecular formula is the actual number of atoms present in the compound. Here, we will discuss more about the E.F. and molecular formula of the compound. What is empirical formula E.F. is the simple whole number ratio of elements in the […]
What is mole concept and how to find the mole of an element
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 […]
What is the law of chemical combination
What are the different laws of chemical combination ? We study the different aspects of chemical reactions in the various chemical combinations. Law of conservation of mass : Laws of chemical combination In all physical and chemical changes, total mass of the system remains constant. It means matter is neither created nor destroyed. Physical changes […]
