Chapter overview. One characteristic property of transition elements is that they have variable oxidation states. Guide students to sort cards into elements and compounds (but do not use the words elements or compounds). The formation of compounds whose color is due to d–d electronic transitions. Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. Define density and tell how it relates to an object sinking or floating in water (the density of water= 1g/cm3). This property of transition elements is in marked contrast to that of the s- and p-block elements, which often yield white compounds. The lightest of all gases, hydrogen combines with other elements -- sometimes explosively -- to form compounds. Country, state or city - 2.
