What did de Chancourtois do to contribute to the periodic table?
It was Lavoisier who wrote the first extensive list of elements - containing 33 elements. He distinguished between metals and non-metals, dividing the few elements known in the 1700's into four classes.
How many elements were there on the periodic table in 1960?
There were 102 known elements on the periodic table in 1960.
What are the elements of radioactivity?
Some of the elements on the Periodic Table are Radioactive. This means that their nuclei decay to form other elements in a decay chain. There are currently 33 known radioactive elements of which 20 are currently produced synthetically.

What year was the periodic table published in?
The first slightly inaccurate Periodic Table of Elements was invented in the mid 1800's. Then Henry Mosley found the mistakes and re-corrected them in the early 1900's, which now is our current periodic table that we use.
What addition of elements make up an atomic number of 33?
The atomic number 33 is for arsenic (As); the nucleus contain 33 protons and 42 neutrons.
How many elements were there on the periodic table in 1960?
There were 102 known elements on the periodic table in 1960.
Which of these elements can be found in the same period as the element potassium?
arsenic 74.922 AS 33

Why were there only 33 elements in the first periodic table?
Because that's how many had been discovered at that time.
Where to get black dragon egg on dragon village?
You can get it either by getting Dark Elements, get it by getting a Random Dragon Egg, or you could get it when you "discover" 33 fully grown dragons in your dragon book.
