What are Atomic orbitals?


Open in App
Solution

Atomic orbital:

  • An atomic orbital is a mathematical phrase that defines the position and wave-like behavior of an electron in an atom.
  • Orbitals are also the 3d space where the probability of finding an electron is maximum
  • An atomic orbital's name is usually a combination of the primary quantum number (n) and the azimuthal quantum number (l).

Possible Atomic Orbitals with n values ranging from 0 to 5:
