Compounds contain more than one kind of atoms (more on atoms, later). It cannot be separated into constituent atoms by simple methods. Eg: common salt (NaCl), Sodium carbonate (Na2CO3). Mixtures Mixtures are a combination of two or more substances, which when combined, each substance retains...

Elements, compounds and mixtures A mixture consists of 2 or more elements or compounds not chemically combined together The chemical properties of each substance in the mixture are unchanged It is possible to separate the substances in a mixture by physical methods, including distillation ...
Compounds and mixtures like water or stainless steel are not elements. But they are made of elements. What elements are in Group 7? The elements in Group 7 are called the halogens. They are highly reactive non-metals. They include fluorine, chlorine, bromine, iodine, and astitine.What...

The name indicates the mass of an atom, expressed in atomic mass units (amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass in always very close to themass (or nucl...
