Hydration.
Compounds that form when an element such as aluminum or iron combines chemically with oxygen are called oxides. Oxide minerals are used to make products such as abrasives, toothpaste, cement, and paint.
Iron belongs to the mineral group called "native elements."
When two or more elements combine chemically, it is called a chemical compound. In a chemical compound, the elements are bonded together in specific ratios to form a new substance with unique properties.
Two or more substances that are not chemically combined are called mixtures. Examples include air, saltwater, and soil.
The rare earth element discovered in 1789 is yttrium. It was discovered by Swedish chemist Johan Gadolin in a mineral called ytterbite, which was later renamed as yttrium in honor of the village Ytterby in Sweden where the mineral was found.

ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
The ease and speed in which an element combines or reacts with other substances is called reactivity. Reactivity is a measure of how readily an element undergoes a chemical reaction.
A mineral that is made up of only one element is called a native element. Examples include gold, silver, and diamond.
It is an elemental mineral.
This is a chemical element as gold or platinum.
The chemical reaction in which an element like iron combines with oxygen to form an oxide is called oxidation.
