If you don't have the chart of the activity series handy, you can also use trends in the periodic table to predict the reactivity of a metal or nonmetal. The most reactive metals belong to thealkali metalselement group. Reactivity increases as you move down the alkali metals group. The in...
We began to twig that something similar was going on with the chemical elements more than 150 years ago. Scientists even called it the law of octaves. And it is this repetition in the properties of the elements thatthe periodic tablecaptures so beautifully. Similar elements end up stacke...
Metals are on the left of the table, metalloids are in the middle, and nonmetals are on the right. Each square of the periodic table contains information about the element. Who invented the Periodic Table? The Periodic Table was invented byDmitri Mendeleevin 1869, who was the first scientist...
