– Discovered elements by passing electricity through a molten solution of their compounds. Section B: History of the Periodic Table. Dobereiner. Triads: a group of 3 elements which had similar physical & chemical properties with the atomic weight of the middle element being halfway between the other two. Example of a triad: lithium, sodium ...
Which element have the most similar chemical properties?
Obj. 3.2 Predict similarities in properties of the elements by using the periodic table. Elements within a column (called a group or family) have similar properties. Obj 3.3 List the properties of groups of elements. Group Name Valence electrons Traits 1 Alkali metals 1 React vigorously with water.

It is called the Periodic Table because elements with similar properties appear at regular intervals. Elements is the same group have similar chemical properties because they have the same number of electrons in their outer shell. Before electrons, protons and neutrons were discovered, scientists put the elements in order of their atomic weights.
