You have learned how to write the electron configuration of an element by looking at its location on the periodic table. use the periodic table tool to look up the positions of the following elements and write down their electron configurations, first without looking at the element’s quick facts, and then checking quick facts to see if you were right. explain how you determined its configuration from its position on the table.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
