Matter (matter) is any substance (whether living or non-living) that occupies sodium chloride space (occupies space) and has a mass (mass). In other words, matter is any substance that has the volume (volume) and mass.
When a drop of blue ink falls into the water in a beaker, blue color ink is spread throughout the water. This indicates that the ink is composed of particles in motion (particles in motion). When the gas pipe in the lab opened, the smell of gas can be detected immediately. This indicates that the gas also is made up of particles in motion.
Compounds sodium chloride (compounds) contains more than one element. The elements in a compound that not only mixed with each other, it is also coupled with a strong power called chemical bonds (chemical bond).
Molecules can also consist of atoms of two or more elements are not the same, eg water molecules (H 2 O), which consists of two atoms of hydrogen and one atom of oxygen, and carbon dioxide (CO 2), which consists of one atom of carbon and two atoms oxygen.
However, some compounds composed of atoms or groups of atoms that carry a positive or negative charge. Charged particles (charged particle) is called ion. For example, sodium chloride salt, NaCl, made up of sodium ions (Na +) and chloride ions (Cl -). Rust on iron spikes consist of iron (III) (Fe 3+) and oxide ions (O 2-).
Neutral particles consisting of electrons moving around the nucleus is made up of protons and neutrons. The simplest particles and unstable unless noble gas atom. Example: a magnesium atom, one atom of carbon, etc.
Particles in an element may be an atom or molecule. In metals and noble gases, particles exist as atoms. For most non-metallic elements, atoms are joined to each other to form molecules. Nonmetallic element particles usually exist as molecules. For example;
Ferrous metal is an element that contains only one type of atom, namely iron atom. Oxygen is a non-metallic element that contains one type of atom, namely oxygen atom. Two oxygen atoms combine to form one molecule of oxygen. Therefore, the particles in the oxygen gas is molecular oxygen, O 2. Non-metallic elements such as hydrogen, nitrogen, chlorine, phosphorus, sulfur, bromine, iodine and fluorine sodium chloride also contain particles of molecules.
Air is composed of covalent compounds as a molecule formed from a combination of oxygen atoms and hydrogen atoms, sodium chloride ie H 2 O. Common salt (sodium sodium chloride chloride) is an ionic compound because it consists of sodium ions and chloride sodium chloride ions are formed from the elements sodium and chlorine elements sodium chloride respectively.
