Science > Chemistry > Atomic Structure > Problems Based on Atomic Number, Mass Number, and Neutron Number In this article, we shall study to solve problems based on the calculation of atomic number, atomic mass number, and neutron number Atomic number (Z) : The number of protons (positive charge) present in the nucleus of an […]
Science > Chemistry > Atomic Structure > Quantum Numbers and Quantum Model of an Atom In this article, we shall study the concept of quantum numbers and the model of an atom based on the quantum numbers. Concept of Quantum Numbers: In 1926, Erwin Schrodinger put forward a theory of atom called as a quantum […]
Science > Chemistry > Atomic Structure > Quantum Numbers and Shapes of Orbitals In this article, we shall study the concept of quantum numbers and different types of orbitals and their shapes. Difference Between Shell, Subshell, and Orbital: All electrons that have the same value for n (the principal quantum number) are in the same […]

Science > Chemistry > Atomic Structure > Electronic Configuration The distribution of electrons in various shells and orbitals of an atom is known as electronic configuration. Generally electronic configuration is given by nlx. Where n is shell number, l is subshell and x are the number of electrons. Aufbau Principle: The arrangement of the electrons […]
