Electron configuration representation

Postby Marie_Bae_3M » Fri Oct 14, 2016 1:47 pm

Hi,
Does it matter whether we have to use the previous noble gas in brackets to shorten the e- configuration representation of an element X or if we could use any element prior to that element X? Thanks :)

For the purposes of this class, it is best to use the previous noble gas in brackets for shorthand electron configurations. Using other elements is not as practical because you would most likely confuse yourself by using an element in the middle of the period because it would become more difficult to determine the subshells within that period. Using the previous noble gas is preferred because then you only have to worry about coming up with the electron configuration by looking at the elements that precede and element X in the same period.
