Oxygen is one of the most abundant elements in our universe. It occurs in our earth's atmosphere, ocean's, and land. Throughout the universe, it is inside stars, planets, and in everything around us.
everywhere. when there are trees in that area
Galactose
Yes. It is found in rocks, and has the chemical formula CaCO3 . It's a form of limestone.
Is the food
Iron is found combined with Oxygen, in the form of Iron Oxide (also known as Rust).
If you mean a naturally occurring element, yes. However it is reactive and therefore not usually found in the pure metal form, instead it is found in compounds as ore.
The term is "minerals." Few elements are found in their pure elemental form, and they are mostly metals.
Yes. Water is a naturally occurring substance.
Naturally occurring (it is an element), the metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
Germanium is a naturally occurring element, but does not occur in pure form on the Earth (only in compounds).
yes. If the metal is reactive enough then oxygen naturally forms compounds.(oxides)
Oxygen has three naturally occurring isotopes: 16O, 17O, and 18O. The most abundant is 16O, with a small percentage of 18O and an even smaller percentage of 17O.
