Evolution of the Periodic Table
This storyboard does not have a description.
I'm Johann Dobereiner and I want to sort all the elements into groups of three called triads!
Your findings are just a coincidence. Why should the properties of elements be connected to their atomic mass?
The atomic mass of the middle element in each triad is the mean of the other two in the triad. The triads are chemically similar.
But not all of the known elements can fit into your scheme. Scientists will not take you seriously.
I am John Newlands and I think the elements should be sorted into octaves like a musical scale.
That's a silly idea, what do elements have to do with music? It's all just chance that it works for the first 17 elements.
I am Dmitri Mendeleev and the idea of the periodic table came to me in a dream. There are lots of elements that we don't know and I have predicted them.
Your 'Periodic Table' does sound believable but I'm not sure about the elements you predicted.
Aha! My predictions are correct! This proves how there are more elements that we don't know about. My way of ordering the elements by relative atomic mass is correct!
This is brilliant. We will name an element after you for your amazing discoveries. It will be called Mendelevlum with the atomic number of 101.
