The short hand configuration is also called noble gas configuration because it mimics the electron configuration of noble gases, which are chemically stable and have full valence shells. By using noble gas configurations, we can easily represent the electron arrangement of elements without writing out the entire electron configuration.
The long-hand electron configuration for francium is [Rn] 7s1, while the short-hand configuration is Rn.
[Ne] 3s2 3p5 ----------------
The long electron configuration for manganese is 1s2 2s2 2p6 3s2 3p6 3d5 4s2.
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^1 Short-hand version: [Ne] 3s^2 3p^1 Note: The "^" symbol means the the following number is in the form of a superscript.
[Ne]3s2

The electron configuration for an atom with 0 electrons is empty, as there are no electrons present to occupy energy levels or orbitals.
The electron configuration of nobelium is:1s22s22p63s23p63d104s24p64d104f145s25p65d105f146s26p67s2
The electron configuration of Tin (Sn) is [Kr] 4d^10 5s^2 5p^2.
The long hand electron configuration for Chlorine is: 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, so its configuration fills up to the 3p subshell with 5 electrons.
