Question

Identify the element indicated by each electricity configuration how do you do it?

1s22s22p6

Answer 1

1s2 2s2 2p6 `->` neon (Ne).

Explanation:

By the way, it's not electricity configuration - it's electronic configuration. The root word is "electron", the orbitals of which is described by 1s2 2s2 2p6.

As for the best way to determine the element purely based on its electronic configuration, it is difficult for elements beyond 18 which is argon (Ar).

For elements below proton number 18, if the electronic configuration is given to be the element's ground state, find the largest number that is in front of the letters s or p. That number will give you a clue of the Period the element belongs on.

Next, add up the numbers after the letters that are behind the above number. This number would be the number of valence electrons present in an atom of the element. This number also tells you which group the element is in (1, 2, 13, 14, 15, 16, 17 or 18, corresponding with 1, 2, 3, 4, 5, 6, 7 or 8 electrons).
