How Do You Locate A Family On Periodic Table?
The periodic table lists all known chemical elements. Historians credit Russian scientist Dmitri Mendeleev with creating the chart back in 1869. Currently, the periodic table contains 117 elements. The table orders elements according to their atomic numbers. An atomic number is the number of protons, or positively charged particles, within the nucleus of an atom. An element family, also referred to as a group, is a set of elements that share the same outer-electron shell pattern. Elements that share identical outer-electron shells tend to have shared properties. In all, there are 18 families in the periodic table. Step 1 Number each column of the periodic table from left to right. Step 2 Locate a column of elements. Step 3 Check the corresponding number you wrote up top. This is the elemental family. For example, the element lithium is part of group 1, or family 1, which is sometimes referred to as the alkali metals, or lithium family. Family names used to rely on a system that used a
