Document Summary

Are different structural modifications of an element; the atoms of the element are bonded together in a different manner: allotrope, different allotropes cab be used for many different applications, elements can also excite electrons using electricity, which in turn generates electricity, elements also have a different range of behaviors such as reactivity. , we label the compound first by mentioning the metal or (we do not have to indicate how many of each element there are because ions have particular charges and must combine in specific ratios: binary molecular compounds many of each atom are present such as mono , di , tri , etc. (2 non metals), we add prefixes to indicate how (we do have to indicate how many of each atom is present) (we also have to use prefixes mono for one, di for two, and tri for three , polyatomic ions.
