Most elements are stable with eight (8) valence electrons. True or False
Elements react in order to gain, lose, or share electrons. True or False
I wonder about your chemistry teacher and the wording here.
1) Most elements do not have eight outer electrons, they have the same number of electrons as protons, and they are quite stable this way. Look at the periodic table. Now when elements combine, they tend to form compounds that gather filled valence shells (ie 8 electrons) around each atom nucleus. I have no idea which your teacher was thinking on.
b. Elements react chemically by forming electron bonds, by sharing, losing, or gaining electrons in new electron configurations.
Good luck in chem.
