Atomic Structure

Isotopes are crucial for various scientific applications, including medical imaging, cancer treatment, carbon dating in archaeology, and tracing environmental changes.

Bohr’s model introduced quantum mechanics into the atomic structure, proposing that electrons orbit the nucleus in fixed paths or shells and can jump between these shells by emitting or absorbing energy.

Ernest Rutherford discovered the nucleus of the atom and proposed that atoms consist mostly of empty space, with a dense central nucleus.

J.J. Thomson discovered the electron in 1897 during his experiments with cathode rays.

Atomic structure refers to the arrangement of protons, neutrons, and electrons within an atom. Protons and neutrons form the nucleus, while electrons orbit this nucleus.
