In the year 1869, sixty-three elements were known. Out of the 92 naturally-occurring elements, the following were yet to be found:

  • Helium
  • Neon
  • Argon
  • Scandium
  • Gallium
  • Germanium
  • Krypton
  • Technetium
  • Xenon
  • the Lanthanoids*
  • Hafnium
  • Rhenium
  • the Radioactive Elements**

*With the exception of lanthanum, cerium, and terbium.

**With the exception of thorium and uranium.

How many known elements were there in 1789?

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.

How many elements are known to man kind?

There are 92 elements that exist in nature*. Every heavier element has decayed before our time.Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements, 112 of which have been confirmed and are named (or in the process of being named).*If you extend the term "nature" to other planets and stars, than you will occassionally find more elements.

What did the world know about elements before 1860?

Before 1860, the world knew about the existence of around 60 elements, such as hydrogen, oxygen, carbon, and gold. These elements were known based on their properties and occurrence in nature. However, the understanding of elements and their classification underwent significant advancement with the development of Dmitri Mendeleev's periodic table in 1869.
