Document Summary

2. 6 valence electron and the octet rule. Called inert as they don"t readily bond to other elements. How many valance electrons are in the following. Elements usually react in such a way as to attain the electron configuration of the noble gas closest to them in the periodic table. Elements on the right side of the table move right to the next noble gas. Elements on the left side move backwards to the noble gas of the previous row. Atoms will gain, lose, or share electrons in chemical reactions to attain this more stable energy state. Elements in families other than the noble gases are more reactive. Strive to achieve a more stable electron configuration. Change the number of electrons in the atom to result in full s and p sublevels. Stable electron configuration is called the noble gas configuration. Electrically charged particles that result from a gain or loss of one or more electrons by the parent atom.
