When a nonmetal becomes an ion it _______ electrons, and becomes ______.
As you go down a group, the atomic radius gets_________, and as you go across a period the atomic radius gets __________. Metals __________ electrons, and nonmetals _____ electrons. An oxygen atom will ____ electrons when it becomes an ion.
Light bulbs have a _____________ inside of them made of the element ___________. This element is used because it has the highest __________ ___________. This metal glows _________ hot when the light turned on. The metal piece will last a long time if the bulb is not broken, because the inside of the bulb is filled with _________ gas which is ________________. However, if the glass is removed, the piece of wire burns up quickly because it is surrounded by _________ gas which is very reactive.
