Ma'am/sir how do you do energy shells for science.

check_circleExpert Solution
Step 1

An atom is mainly composed of three sub-particles; electrons, protons and neutrons. These particles are arranged in a certain way in the atom and provide electrical neutrality to the molecule. Electrons are placed in different energy levels of an atom.

Step 2

The energy levels of electrons in an atom can be explained with the help of different quantum numbers.

  • Principal quantum number ‘n’- It represents the number of shell in an atom. It defines the size of atom and also related to another quantum number ‘l’.
  • Azimuthal quantum number ‘l’ - It represents the number of sub-shell in an atom. The values of ‘l’ can be from 0 to n-1. Here 0 is for s-subshell, 1 is for p-subshell, 2 is for d-subshell and 3 is for f-subshell.
  • Magnetic quantum number ‘ml’- It represents the number of orbitals and can be from -l to +l including 0.
  • Spin quantum number- It indicates the spin of electrons and can be +1/2 or -1/2.
