Ion Electron Configurations When we write the electron configuration of a positive ion, we remove one electron for each positive charge: Na → Na+ 1s2 2s2 2p6 3s1 → 1s2 2s2 2p6 When we write the electron configuration of a negative ion, we add one electron for each negative charge: ...

1 3. The Noble gas shorthand configuration (a short cut of the full configuration) Look at the Noble gas (element in group 8A) that comes BEFORE the element of interest. Example The Noble gas before Na is Ne.Na would be [Ne] 3s 1 (see how the 1s 2 2s 2 2p 6 is substituted...
Scientists show the arrangement of electrons in energy levels and energy sublevels through electron configurations. We can determine the electron configuration of an element using the periodic table. Phosphorous fills up the first two energy levels and lands in the p sublevel on the 3rd row. It ...

lonic bonding in this section, we will look at ionic bonding the transfer of one or more electrons from a metal to a nonmetal. (2) write the electron configuration for the alkali metals (li, na, and k). li: na: k: what is the similarity amon...
What is the electron configuration of Na^+? A S atom has an electron configuration of 2.8.6. What is the electron configuration of an S2- ion? What is the valence electron configuration for the element in Period 4, Group 6A? What is the valence shell electron configuration of a pnictogen...
