Geometrical representation of the electronic distribution in sodium atom is shown below.

What is an atom?

  • Atom is the smallest basic unit of elements.
  • Constituents of atom are protons, electrons and neutrons.

What is an electron?

  • It is the negative charged particle in an atom.
  • It is equal to the atomic number.
  • It revolves around the nucleus of atom and different shells/orbits.

What is a proton?

  • It is a positively charged particles posited in the nucleus of atom.
  • It adds up to the atomic mass number of atoms.

What is neutron?

  • Neutron is neutral charged particles of atom.
  • These are posited in the nucleus of atom and it adds up in the mass number of atom.

In the figure below:

  • Atomic number of sodium is 11.
  • Atomic mass of sodium is 23.
  • Number of protons is 11 and number of neutrons is 12 inside the nucleus.
  • 11 electrons are revolving around the nucleus in orbits of different energy states.
  • Electronic configuration is (2, 8, 1). K-Shell has 2 electrons, L-Shell has 8 electrons and 1 electron in M-Shell.
