Document Summary

An electronic configuration that is characterized by two electrons in the valence shell of helium and eight electrons in the valence shell of all other group viii a noble gases. A representation of an atom or ion in which the elemental symbol represents the atomic nucleus and all but the valence-shell electrons. The valence electrons are represented by dots arranged around the elemental symbol. Write an electronic configuration for the atom and identify the valence electrons as those having the largest n value in the configuration. A simpler alternative for representative elements is to refer to the periodic table and note the group to which the element belongs. The number of valence electrons is the same as the roman numeral group number. Examples: calcium, ca, is in group ii a. Potassium, k, is in group i a and so it has one valence electron. Aluminum, al, is in group iii a and so it has three valence electrons.
