Elements are made of one type of atom, either by itself or bonded together to form a molecule. Compounds are molecules that are composed of two, simpler substances. They are made of more than one type of atom chemically bonded together. Substances cannot be broken down into smaller parts ...
Chemical substances can be solids, liquids, gases, or plasma. Pure chemical compounds are substances composed of bonded molecules or ions. For example, pure water is s chemical substance since it always has the same ratio of hydrogen to oxygen. However, seawater is a mixture since it contains ...

aThe masses of atoms and molecules are characterized by using quantities known as the relative atomic mass of an element (the atomic mass in short) and the relative molecular mass of a substance (the molecular mass ) 原子和分子大量描绘的是为使用数量以元素(原子质量的原子量简而言之)和物质的...
For instance, covalent (network) solids are made of atoms while molecules solids are made of molecules.Answer and Explanation: Rubidium iodide is an ionic compound that consists of rubidium ions and iodide ions. So the solid is made of ions that have ionic...
