Metallic bonding theory
Metallic bonding Metallic bonding (metal-metal): This type of bond is given in all pure metals and most alloys. In a metal, atoms are very close to each other forming what is called a […]
Kinematics theory
Kinematics Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. When we study the motion […]
Chemical calculations theory. States of matter aggregation.
States of matter aggregation The matter is present in the nature in three different States of matter aggregation: solid, liquid and gas. Solids have fixed shape and volume. Liquids have fixed volume, but its […]
