There is no founder for the subject matter of physical science, there are many scientists' contributions though.
117 know ones (some are yet to be discovered)
There have been many advancements in the science fields over the years. With all of the technological and equipment advancements, scientists have discovered many new things and proven many theories.
It was Albert Ghiorso who discovered or co-discovered the most elements, 12.As a member of both the Manhattan Project, and later a researcher at UC Berkeley, Ghiorso and his teams uncovered elements 95 (americium) through 106 (seaborgium). All of them are radioactive; and all of them are man-made, having long since decayed in nature.Of them, americium has seen the greatest commercial use, being found in most modern smoke detectors.
About 28 elements were discovered in the laboratory. But after the man made preparation some elements were discovered also in nature in very extremely traces: Pm, Tc, Pu, Np, Am, Cm, Bk.
As of 2006, scientists know of 117 different elements
Scientists have discovered and created a large number of elements thus far. Currently, there are 118 confirmed elements on the periodic table, with the first 92 occurring naturally and the rest being synthetic elements created in laboratories.
What is a positive atomic partical
The elements from the atomic number 98 to 118; but many other isotopes were created by scientists. Also some elements as Np, Pu, Bk, Am, Cm, Tc, Pm were for the first time obtained in laboratories and only after they were discovered in the nature at very low traces.
Many of the first discovered elements were named by their discoverer or the location where they were discovered, such as hydrogen, named by Antoine Lavoisier, and uranium, named after the planet Uranus.
There are currently 38 radioactive elements that have been discovered. These elements have unstable nuclei that undergo radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays.
Scientists have identified 118 elements, with the most recent addition being tennessine in 2016. These elements span the periodic table and have unique properties that contribute to their classification.
No one knows how many elements are left to discover.
a lot probaly over 1000 elements
There were 118 discovered elements in the periodic tableÊas of 2008. However, some of these elements still have ongoing disputes.
Two elements were discovered in 1830: terbium and cerium. Terbium was discovered by Swedish chemist Carl Gustaf Mosander, while cerium was independently discovered by Swedish chemist JΓΆns Jacob Berzelius and German chemist Martin Heinrich Klaproth.
Surprisingly, most are.
