Question

Elements and compounds are all around us. Elements are made up of atom or atoms of the same kind. They are the simplest type of matter and cannot be broken down into components. Each element is made entirely from one type of atom. Each element is unique, and no two elements have the same set of properties. Some are in the same state, but they have different properties. Some elements are metals like iron, gold, and silver. Others are nonmetals like Nitrogen, Oxygen and Hydrogen There are elements that are metalloids like Boron, Silicon and Germanium. combination of two Compounds are more elements like water which is a combination of Hydrogen and Oxygen; salt which is made up of sodium and chlorine; and rusts formed when an iron reacts with oxygen. Compounds can be broken down into its components through a chemical process and formed when two elements are combined. It has unique properties that are different from the properties of the or elements that make them up. Can you name new metallic elements and set of compounds that is not four in the selection above? Write it inside the box below.
