The letter "S" represents a shorthand way of writing the element sulfur. This abbreviation is also known as | Chemical symbol |
As you move from top to bottom on the periodic table... | The number of energy levels increases |
Elements on the left hand side of the periodic table ____ electrons, while elements on the right hand side typically _____ electrons | lose, gain |
Elements in the helium family are called noble gases because they | Do not need to gain or lose electrons |
An element has 12 electrons. How many valence electrons does it have? | 2 |
Elements in the Carbon Family form many different bonds because | They can lose or gain 4 electrons |
