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 elements were there in 1860?
63 elements had been discovered so far.
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.
How many different elements are there in sodium hydrogencarbonate?
Sodium hydrogencarbonate, also known as sodium bicarbonate or baking soda, contains three different elements: sodium (Na), hydrogen (H), and carbon (C).
What are the total number of elements discovered till date?
As of now, there are 118 known elements on the periodic table. These elements range from hydrogen (element 1) to oganesson (element 118).
How many elements were there in 1860?
63 elements had been discovered so far.
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.

Before 1860 were the elements not organised well?
Before 1860 there have been some simpler attempts to organize the chemical elements.
There are how many currently known elements?
There are currently 118 known elements.
What were the elements Bunsen discover?
Robert Bunsen, a German chemist, is known for discovering the elements cesium and rubidium in 1860 by using spectroscopic analysis. These elements were identified using the characteristic spectral lines emitted by their atoms when heated in a Bunsen burner flame.
Why were scientists frustrated by the organization of the elements in the early 1860?
beacause no one had organized the elements yet: )
How many elements have been observed as of 2008?
117 elements
