Question
Mendeleev wanted to find a pattern amongst all the elements that were known at his time. State which two features he used to organise the elements.
Solution
Mendeleev used two main features to organize the elements:
-
Atomic Weight: Mendeleev arranged the elements in order of increasing atomic weight. This means that he started with the element that had the smallest atomic weight and ended with the element that had the largest.
-
Chemical Properties: He also grouped elements together that had similar chemical properties. This means that elements that reacted in a similar way or had similar behaviors were grouped together.
These two features formed the basis of his periodic table.
