chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical bonding are called valence electrons. Bonding electrons: The valence

easily bent or twisted. It had a metallic surface and was brittle. It was silver in color. A flame from a Bunsen burner was held to the Mg‚ and it ignited‚ giving off a brilliant white light. Looking directly into the light resulted in temporary blindness‚ which would explain the warning on the procedures that strongly suggested not looking directly into the light. After the flame had extinguished itself due to lack of fuel‚ the Mg had turned from a metallic strip to an off-white powder‚ which

There are 3 types of metals for electricity conducting: metallic conductor‚ semiconductor‚ and superconductor. Metallic conductors allow the free flow of ions and electrons through a sample; and its conductivity decreases as the temperature increases. Semiconductors allow the flow of both ions and electrons through the sample but not completely free; and its conductivity increases with increasing temperature. Superconductors are a class of metallic conductor whose resistance drops to zero suddenly below

In general‚ the ability of a substance to conduct energy‚ in this case heat‚ is directly related to its density. Air‚ being much less dense than the metallic substance‚ conducts energy to a lesser degree. It is also one of the fundamental properties of metallic substances to conduct energy which is related to its atomic structure. Also‚ air can get really hot‚ but it just can’t transfer that energy to someone hand as well as metal. Actually‚ aluminum pan
