FAMILIES STICK TOGETHER
We just covered the columns and rows of the periodic table. There are also other, less specific, groups of elements. These groups are all over the table. Scientists group these families of elements by their chemical properties. Each family reacts a different way with the outside world. Metals behave differently than gases and there are even different types of metals. Some don't react, others are very reactive, and some are metallic.
Usually, the columns of the periodic table are used to define families. The inert gases are all located in the far right column of the table. That column is labeled Group Zero. The other possibility that can happen are elements in a series. Good examples of a series of elements in the same family are the transition metals. The thing to remember is... A family of elements can be found in several ways. You need to run tests and study the elements to determine their properties. Only after that testing, can you determine what family an element belongs in. EXAMPLES OF FAMILIES - Alkali Metals - Alkaline Earth Metals - Transition Metals - Halogen Gases - Inert Gases (Noble Gases) EXAMPLES OF PHYSICAL PROPERTIES - Density - Boiling Point - Melting Point - Conductivity - Heat Capacity EXAMPLES OF CHEMICAL PROPERTIES - Valence - Reactivity - Radioactivity
