NEET-CHEMISTRY Atoms and Nuclei

Atoms and nuclei are fundamental topics in NEET-CHEMISTRY that are concerned with the structure and properties of the building blocks of matter. Atoms are the basic units of chemical elements, and are composed of protons, neutrons, and electrons. Nuclei, on the other hand, are the central part of an atom that contains protons and neutrons, which are collectively known as nucleons.

The NEET-CHEMISTRY syllabus covers the following topics related to atoms and nuclei:

1. Atomic structure: This includes the discovery of subatomic particles, such as electrons, protons, and neutrons, and their properties. It also covers the Bohr model of the atom and quantum mechanical model of the atom.
2. Electronic configuration of atoms: This involves understanding the distribution of electrons in different energy levels or shells around the nucleus of an atom.
3. Atomic spectra: This topic involves the study of the characteristic spectra emitted or absorbed by atoms as a result of electronic transitions within the atom.
4. Radioactivity: This includes the different types of radioactive decay, half-life, and nuclear fission and fusion.
5. Nuclear energy: This involves the study of the production of energy from nuclear reactions and the different types of nuclear reactors.
6. X-rays and their production: This includes the production of X-rays and their properties.

A strong understanding of atoms and nuclei is essential for various fields such as nuclear physics, material science, and radiation therapy. It is also necessary for the study of other fields of NEET-CHEMISTRY, such as chemical bonding, chemical kinetics, and chemical thermodynamics.

2. 1895: Wilhelm Conrad Roentgen discovered X-rays, which were found to have the ability to penetrate through matter and leave an image of the internal structures.
3. 1897: J.J. Thomson discovered the electron, the first subatomic particle, using cathode ray experiments.
4. 1904: Thomson proposed the “plum pudding” model of the atom, which suggested that electrons were embedded in a positively charged mass.
5. 1911: Ernest Rutherford conducted the famous “gold foil” experiment, in which he discovered the nucleus by bombarding thin gold foil with alpha particles.
6. 1913: Neils Bohr proposed the first quantum mechanical model of the atom, which explained the distribution of electrons in different energy levels around the nucleus.
7. 1932: James Chadwick discovered the neutron, which is a neutral subatomic particle present in the nucleus.
8. 1942: Enrico Fermi and his team initiated the first controlled nuclear chain reaction in Chicago, marking the beginning of the nuclear age.
9. 1950s: The development of particle accelerators and detectors made it possible to investigate the properties and structure of atomic and subatomic particles in more detail.

Today, the study of atoms and nuclei remains a vibrant area of research, with important applications in fields such as energy production, materials science, and medicine.
