It is not possible for us to measure the exact position and exact momentum of electrons simultaneously is the statement of _?

Correct answer: C. Heisenberg

  • A. de-Broglie
  • B. Mosley
  • C. Heisenberg
  • D. Neil Bohr

Explanation

De Broglie's statement, also known as the De Broglie hypothesis, states that every object or particle in motion, regardless of its mass, has a wave-like nature associated with it. Moseley's statement, also known as Moseley's law, is a relationship between the wavelength of characteristic X-rays emitted by an element and its atomic number. The Heisenberg uncertainty principle, also known as the uncertainty principle, is a fundamental principle in quantum mechanics that states that it is impossible to simultaneously determine certain pairs of physical properties of a quantum particle, such as its position and momentum, with arbitrary precision. Niels Bohr was a Danish physicist who made important contributions to the development of atomic theory. One of his key contributions is the Bohr model of the atom, which describes the structure of atoms in terms of discrete energy levels.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
