As of 2006, scientists know of 117 different elements
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.
63 elements had been discovered so far.
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 Jöns Jacob Berzelius and German chemist Martin Heinrich Klaproth.
Many elements were not discovered before the 17th century because the technology and scientific methods necessary for their discovery were not yet developed. Additionally, the concept of elements as fundamental building blocks of matter was not fully understood until the advent of modern chemistry in the 18th century.
How many known elements were there in 1789? Short answer = more than 63 Longer answer = In the 1860's Mendeleev organized the 63 known elements. After this organization there was a boom of new elements being discovered (because we now knew what we were looking for). I'm sure further research would turn up a better answer.

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.

No one knows how many elements are left to discover.
Plasma was discovered in Tokyo Japan by the scientist Yoshi Hiragotima during his MANY experiments.

There were 118 discovered elements in the periodic tableÊas of 2008. However, some of these elements still have ongoing disputes.
At least 112.
Scientists have made over 30 elements in the laboratory, known as synthetic elements. These elements are typically created by nuclear reactions and are usually unstable and decay quickly. Examples include elements like neptunium, americium, and tennessine.
Approx. 25 chemical elements were known in 1800.
In 1870, 63 elements had been discovered.
