The relationship between the number of electrons in an atom's outer shell and the atom's tendency to bond is called the octet rule. What can you infer about the meaning of "octet?" It refers to negative charges. It refers to sets of eight valence electrons It refers to explosive substances. It refers to different states of matter.
Try these: square Ca+square O_(2)arrow square CaO
How many valence electrons does Helium Have? 2 Valence electron 3 Valence electron 5 Valence electron 4 Valence electron 1 Valence electron
