etc. Group 1A (1), the alkali metals all end is s1. What period the element is in determines the 1st number. Example: H ends in 1s1 (even though H is not a metal, it resides in this group because it also has one valence electron) Li ends in 2s1 (lithium is in period 2) Na ends in 3s1 ( sodium is in period 3) Electron configuration of every element in the periodic table.

What is wrong about this electron configuration of germanium 2015-02-14 · The element you're looking for is sulfur, or "S". Here's how you can use an element's electron configuration to determine its identity. 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(4) If you add all the electrons decribed in this electron configuration you'll get 2 + 2 + 6 + 2 + 4 = 16 For a neutral atom, the number of electrons it has will match the number of protons in its nucleus, i.e. its atomic number.
