On the Table there will be a key or legend. These colors are often used to show which elements are metals, metalloids, or nonmetals. Sometimes the background colors of the squares mean something else. and physical properties of group 1 elements to their potential use. In this case, that’s moving sodium from a concentration of 10mM to one of 145 mM. Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about. Transport that directly uses ATP for energy is considered primary active transport. The color of the chemical symbol might mean something, too. ATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that was stored in its chemical bonds. For example, potassium's chemical symbol is K. So some of the symbols are tricky to remember. ![]() But some elements were first given Greek or Latin names. The letter or letters are the chemical symbol for the element.
