2. The delocalised electrons in the metal are free to move throughout the entire structure. When attached to an electrical power source, this means the metal can conduct electricity.

3. Metallic bonding occurs when you have a metal in the solid or liquid state. The s and p valence electrons of metals are loosely held. They leave their “own” metal atoms. This forms a "sea" of electrons that surrounds the metal cations.

4. Atoms in metals lose electrons to form cations. Delocalized electrons surround the ions. Metallic bonds (electrostatic interactions between the ions and the electron cloud) hold the metallic solid together. Atoms are arranged like closely packed spheres.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
