Summary of Structure of Atom for Kerala Board Class 10 Science. Key concepts, important points, and chapter overview.
Overview
The Structure of Atom chapter explores how sub-atomic particles (electrons, protons, and neutrons) are arranged within an atom. Building on previous knowledge of atomic models by Thomson, Rutherford, and Bohr, this chapter introduces the modern quantum mechanical model of the atom, explaining how el
Key Concepts
Light exhibits wave properties with wavelength
Light exhibits wave properties with wavelength (λ) and frequency (ν) related by c = νλ. The electromagnetic spectrum includes gamma rays, X-rays, UV,
Energy is absorbed or emitted
Energy is absorbed or emitted in discrete packets called quanta. Energy of radiation is given by E = hν, where h is Planck's constant (6.626 × 10⁻³⁴ J
Electrons occupy stationary orbits of fixed
Electrons occupy stationary orbits of fixed energy around the nucleus. When electrons jump between energy levels, they absorb or emit energy as electr
Electrons don't follow definite paths but
Electrons don't follow definite paths but exist in regions of space called orbitals where probability of finding them is maximum. Position and velocit
Four quantum numbers describe an electron
Four quantum numbers describe an electron: Principal (n) - size and energy; Azimuthal (l) - shape of orbital; Magnetic (ml) - orientation; Spin (ms) -
