Are all elements formed in nature?
While many elements occur in nature, they might not occur in pure or native form. There are only a few native elements. Elements that occur naturally, yet not in native form, include the alkali metals, alkaline earth, and rare earth elements. These elements are found bound in chemical compounds, not in pure form.
How many naturally occurring elements are there?
92 naturally occurring elements
The modern periodic table includes the 92 naturally occurring elements found in earth’s crust and ocean (in green in Fig. 2.7) and two elements, Technetium (Tc) and Promethium (Pm), which are created as byproducts of nuclear reactors (in orange in Fig. 2.7).
Which are man made elements?

How are the elements that make up the Earth formed?
Elements formed – standard science theory All 92 elements on Earth, including those that make up our bodies, were formed at the heart of a star. Small stars like our Sun produce the lighter atoms through fusion reactions. Larger stars with heavier cores make the heavier elements up to iron.
How are all the elements in the universe formed?
As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies. The other 86 elements found in nature were created in nuclear reactions in these stars and in huge stellar explosions known as supernovae. Elements are formed deep within the cores of certain types of star.
How many elements can be found in nature?
Assuming 98 elements can be found, however briefly, in nature, there are 10 found in extremely minute amounts: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; plutonium, number 94; americium, number 95; curium, number 96; berkelium, number 97; and californium, number 98.
Are there any elements that can be synthesized naturally?
These elements can be synthesized naturally. Perhaps the stars create elements much heavier than we ever can, but these elements cannot survive more than a few microseconds — they immediately decay into lighter elements. Man then took the laws of nature into his own hands when the technology sufficed.
