The graph above indicates some trends in the U. By observing the direction our eating habits are going, steps can be taken to help prevent bad eating habits and decrease problems such as high blood pressure and heart attacks. Development of the periodic table has helped organize chemical information in many ways. We can now see trends among properties of different atoms and make predictions about the behavior of specific materials. Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have relatively low attraction for electrons, as indicated by their low electronegativities. By following the trend summary in the figure below, you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal is cesium, which is not found in nature as a free element. It reacts explosively with water and will ignite spontaneously in air.

Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. BMTC Conductor.

Transition metals are actually the various chemical elements that have valence electrons. It means electrons that can promote the formation of chemical bonds in two shells instead of just one. Although the term transformation does not have any specific chemical meaning, it is a convenient name for distinguishing the similarity of the atomic structures and the resulting properties of the elements. They occupy the center portions of the periodic table of elements between the groups on the left and the groups on the right. Image will be Uploaded soon.
