Why does the number of valence electrons matter? The number of electrons in the valence shell determines how an element will bond. If two elements share electrons to fill up their valance shells, they are called covalent bonds. If one element “steals” an electron from another element, those elements no longer have equal numbers of protons and electrons and this they are no longer equal, the element with have a charge. We call elements with charge ions. They are now attracted to each other because they have opposite charges; this is called an ionic bond. We can give an educated guess as to whether an element is likely to bond covalently (share) or ionically (steal) based on where they are on the table. Let’s think about what the columns tell us about the number of valence electrons. If you are an element that is in Group II, you have 2 valence electrons. You would need 6 to complete your shell. How likely is it that another element will share 6 electrons? I think it’s more likely that…
