Many people wonder about the total number of elements present in the Earth’s crust. The right answer to this question is around 118 elements according to the periodic table. There are about 94 elements that are naturally occurring while the remaining are said to be the trans-uranic elements or artificial elements, which are synthesized in experiments where they interact with each other.
The chemical element is the type of an atom. According to the latest information obtained, 118 elements have been identified which are listed under different categories like alkali metals, Alkali earth metals, transition metals, metalloids, Halogens, other metals, other non metals, noble gases and rare earth metals. Each element is different in its properties, appearance, chemical composition and physical state. While some exist in solid state, others can be found in liquid or gaseous state. Some elements exist in free state in Earth’s crust and others can be found in combination with other elements.
According to the studies conducted, it has been said that the present day elements come from mainly three sources – the supernova nucleosynthesis, Stellar nucleosynthesis and the Big bang nucleosynthesis. In simple terms, neucleosynthesis can be defined as the process when the atom nuclei is pressed very close together at high heat so that they overcome their mutual repulsion and produce one heavier nucleus.The first nine elements known to ancient men were gold, silver, copper, iron, lead, tin, mercury, sulfur and carbon.
These are the most commonly used elements, which usually exist, in their pure form. Out of the 118 elements discovered so far, 94 occur naturally on earth and 24 elements are not found on earth and are derived artificially. All artificial elements are radioactive in nature and have a short half-life. Hydrogen, oxygen, sulfur and aluminum are some of the elements that are found in abundance.
