The quantum mechanical model of an atom uses atomic orbitals to describe the location and shape of the orbital in which the electron is present.
Quantum mechanical model of an atom:
- A mathematical equation is used to describe the location and energy of the electron in an atom.
- The electron is treated as a wave around the nucleus of an atom.
- And to locate the electron four different quantum numbers are used.
- These numbers are associated with energy, distance from the nucleus, orientation and, spin of the electron.
- The quantum numbers are:
- Principal quantum number (n): Energy and size of the orbit
- Angular momentum quantum number(l): Shape of the orbital (part of an orbit)
- Magnetic quantum number ([tex]m_l[/tex]): Orientation
- Spin quantum number ([tex]m_s[/tex]) : Electron spin direction
So, from this, we can conclude that the quantum mechanical model of an atom uses atomic orbitals to describe the location and shape of the orbital in which the electron is present.
