Show answer
periodic table
The ordering of all chemical elements.
💡 Did you know? Mendeleev arranged the chemical elements in a table that still hangs in every chemistry room: the periodic table.
All questions with answers
How did Mendeleev originally order the elements?
Show answer
atomic weight
And by recurring properties.
💡 Did you know? Mendeleev originally ordered the elements by atomic weight: the patterns revealed deep connections.
What did Mendeleev boldly predict?
Show answer
undiscovered elements
Along with their properties, e.g. gallium and germanium.
💡 Did you know? Mendeleev predicted the properties of undiscovered elements and was astonishingly right.
What did Mendeleev leave in his periodic table where elements were missing?
Show answer
gaps
For the predicted, still-unknown elements.
💡 Did you know? Where elements were missing, Mendeleev boldly left gaps in his table: later filled exactly as expected.
Which element 101 is named after the creator of the periodic table?
Show answer
mendelevium
An artificially produced, heavy element.
