Elements are considered a non-metal if they lack luster, don’t conduct heat or electricity, and are non-malleable.Elements are labeled as a metal if they have luster, are solid at room temperature, conduct heat and electricity, and are malleable and ductile.Keep in mind that hydrogen can be grouped with either the Halogens or the Alkali Metals because of its properties, so it may appear on either side of the table or may be colored differently.You’ll notice that metals occur to the left of the table, while non-metals fall on the right. Fortunately, most periodic tables use color to indicate whether the element is a metal, semi-metal, or non-metal. You can better understand the properties of an element by recognizing what type of element it is. Distinguish between metals, semi-metals, and non-metals.
