In geology, the crust is the outermost solid shell of  Earth or natural satellite, which is chemically distinct from the underlying mantle.

An element is a substance that cannot be broken down into similar substances.

They also have a symbol which is based on the element’s English or its name of another language.

Examples include: Mercury (Hg) Zinc (Zn) Nitrogen (N)

Chemical symbol: Si Physical state: Solid Colour: Blackish- silverish Uses- Used in glass, ceramics, computers, 

calculators and cement Interesting facts:

First discovered by Antoine Lavoisier in 1787 Found in sand The name originates from the Latin word 'silex‘.

Chemical Symbol: Ca  Physical state: Solid  Colour: Silver Uses- Used in plaster, quicklime, cement, and 

metallurgic and electronic materials. Interesting facts:

Found naturally in limestone, gypsum, and fluorite. 

The name originates from the Latin word 'calcis‘.

Chemical Symbol: Mg Physical state: Solid Colour: Silvery-white Uses- Used in structural alloys, pyrotechnics, 

flash photography, and incendiary bombs. Interesting facts:

It is widely distributed in rock structures and highly reactive.

The name originates from a Greek district called Magnesia.

Chemical Symbol: K Physical state: Solid Colour: Silvery-white Uses- Used in fertilizers and soaps Interesting facts:

It occurs in nature only in compoundsand can only be obtained by electrolysis of its common hydroxide.

It was first discovered by Sir Humphrey Davy in 1807.
