Explanation

Metallic bonds are the force of attraction between positive metal ions and valence electrons that are constantly moving around them.

Metallic bonds occur among metal atoms.

Whereas ionic bonds join metals to non-metals,

metallic bonding joins a bulk of metal atoms.

A sheet of aluminum foil and a copper wire are both places where you can see metallic bonding in action.

Explanation

Smelting uses heat and a chemical-reducing agent to decompose the ore,

driving off other elements as gases or slag

and leaving the metal base behind.

Smelting is a method used in the extraction of metals that involves heating the metal oxide produced from roasting with a reducing agent, such as carbon, to obtain pure metal.

Explanation

Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.

This source of energy can be produced in two ways:

fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together.

Explanation

Aluminum is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon.

Explanation

Nuclear energy originates from the splitting of uranium atoms – a process called fission.

Explanation

Rubies are scientifically known as corundum, a rock-forming mineral and crystalline form of aluminium oxide which is two aluminium atoms and three oxygen atoms (Al2O3) in a close packed hexagonal structure.

Corundum typically contains traces of iron, titanium, vanadium and/or chromium.
