Electric wires are coated to insulate and protect against electric shock. Metals that produce a sound on striking a hard surface are termed sonorous.

Metals such as copper, aluminum, and stainless steel are commonly used for making cooking vessels because of their malleability, ductility, good heat conductivity, and high melting points.

The ability of metals to be drawn into thin wires is known as ductility, and gold is mentioned as the most ductile metal.

The first step is to collect samples of metals such as iron, copper, aluminium, magnesium, sodium, lead, zinc, and any other easily available metal.

Metals, in their pure state, exhibit a shining surface, which is referred to as metallic lustre.
