Quiz on Elements in Chemistry
Elements are pure substances that cannot be broken down into simpler substances by chemical means. Each element is made up of only one kind of atom. There are over 100 known elements, and each has a unique chemical symbol — for example, Hydrogen (H), Oxygen (O), and Iron (Fe). Elements combine to form compounds like water (H₂O) and carbon dioxide (CO₂). The periodic table organizes all elements based on their properties, atomic number, and structure. Some elements are metals, others are non-metals or metalloids, depending on their characteristics.
