What is Atom & Its Structure. #sciencefacts #atom #theory #model

What is atom? The atom is the fundamental building block of matter. It’s the smallest possible particle of matter History of Atomic Theory 1. Democritus (460-370 BCE): Proposed the idea of atoms as indivisible, eternal particles. 2. John Dalton (1803): Developed the modern atomic theory, stating that elements are composed of small, indivisible particles called atoms. 3. J.J. Thomson (1897): Discovered electrons and proposed the “plum pudding” model of the atom. 4. Ernest Rutherford (1911): Conducted the gold foil experiment, leading to the development of the nuclear model of the atom. 5. Niels Bohr (1913): Proposed the Bohr model of the atom, which introduced energy levels and electron shells. Structure of the Atom 1. Protons: Positively charged particles found in the nucleus (center) of the atom. 2. Neutrons: Particles with no charge found in the nucleus. 3. Electrons: Negatively charged particles orbiting the nucleus. 4. Nucleus: The central region of the atom containing protons and neutrons. 5. Electron Shells: Energy levels or regions around the nucleus where electrons are found. Atomic Number and Mass Number 1. Atomic Number (Z): The number of protons in an atom’s nucleus, defining the element. 2. Mass Number (A): The total number of protons and neutrons in an atom’s nucleus. Isotopes and Ions 1. Isotopes: Atoms of the same element with different numbers of neutrons. 2. Ions: Atoms that have gained or lost electrons, resulting in a net positive or negative charge.
