please write a short note on the electronic configuration of metals nonmetals and noble gases.

Hello Mate,
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.
Electron....An electron configuration is the arrangement of electrons within an atom. The electron configuration describes where the electrons are inside orbitals. The structure of the Periodic table of elements is partly based on electron configuration. There are four kinds of electron configurations: s, p, d, and f orbitals.Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus.A The group 2 elements are in the s block of the periodic table, and as group 2 elements, they all have two valence electrons. ... B Thus beryllium has an [He]s 2 electron configuration. The next element down, magnesium, is expected to have exactly the same arrangement of electrons in the n = 3 principal shell: [Ne]s 2.
Electronic configuration of metals -
Always metals have the capacity to donate electrons. They have enough electons in their outermost shell.
e.g. Sodium ( 2,8,1 ). It has one electron in outermost shell so it can donate one electron.
Electronic configuration of non metals -
Non metals always receive electron to attain noble gas configuration.They do not have enough electrons .
e.g. Chlorine ( 2,8,7 ) . It receives one electron to become octet.
Noble gases - They have enough electrons . They need not share and need not receive .
e.g. Argon ( 2,8,8 ).
