Shorthand notation for electron configurations save you time in writing out the configurations for heavier elements. Shorthand notations make use of the fact that the noble gases have full outer electron shells, and some sources call it "noble gas notation" for this reason. Put the chemical symbol...
To simplify the writing of electronic configurations, we can use a shorthand notation that uses the symbol of the previous noble gas in brackets to represent the inner electrons that are in a stable configuration. For example, instead of writing 1s^2 2s^2 2p^6 for neon (Ne), we can writ...
Lewis Structures: Lewis structures are pictoral diagrams of molecules used to demonstrate the arrangement of covalent bonds between atoms. They are determined by trying to satisfy the octet of each atom whilst ensuring that the total number of valence electrons in the molecule overall stays constant....
