The Periodic Table I have chosen from before the 1900's is Rang's Periodic Arrangements of the elements. This representation breaks the elements down into 4 groups, A, B, C, and D. Group A has the strongest positive elements while Group D has the strongest negative elements. Group B has high melting points and Group C is heavy metals with low melting points. This chart breaks up the elements into their characteristics which made it easier to understand the relationship between certain elements. This allows the comparison of positive and negative elements along with melting points.
