Explanation:
Approximately 90 naturally occurring elements have been found in nature.
Elements are the fundamental building blocks of matter, and they cannot be broken down into simpler substances by chemical means. As of my knowledge cutoff in September 2021, there are 118 known elements in total, with 94 of them being naturally occurring or stable elements. Out of these naturally occurring elements, some are relatively abundant in the Earth's crust and are essential for life, while others are rare and occur in trace amounts.
The most abundant elements in the Earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. These elements make up the vast majority of the minerals and rocks that form the Earth's surface.
Some elements, like carbon, hydrogen, nitrogen, and oxygen, are essential for life and are the building blocks of organic compounds, such as carbohydrates, proteins, lipids, and nucleic acids. These elements play a crucial role in the biochemistry of all living organisms.
On the other hand, there are elements that are extremely rare and occur in trace amounts, such as gold, platinum, and iridium. These elements have unique properties and are often valued for their scarcity and various industrial applications.
Elements can be found naturally in various forms, including minerals, ores, gases, and dissolved in water bodies. The study of elements and their properties is central to chemistry, physics, geology, and many other scientific disciplines, as it helps us understand the composition of the Earth, the universe, and the chemical processes that govern our world.
