1 Vitamins and minerals (including antioxidants, such as vitamin A, C, E and selium). 2  Vitamins and minerals are found in all foods, but fruits and vegetables are a particularly good source for some vitamins and minerals.( 3 See below for What vitamins and minerals do.).itamins and minerals are found in most foods, but fruits and vegetables are particularly good sources of many of these valuable compounds.Vitamins and minerals play a vital role in most metabolic processes. Complex interactions make it essential that the status of all vitamins and minerals be kept at optimal levels.
1 Osmium. The densest naturally occurring element on the planet is osmium, a metal in the platinum family with a density of 22.6 grams per cubic centimeter. If that means nothing to you, then youâre normal. By comparison, lead is 11.3 grams per cm cubed.
Density is mass per unit volume Density describes how much mass is in a given volume of a material. Steel has high density; it contains 7.8 grams of mass per cubic centimeter. Aluminum, as you well might predict, has a lower density; a one-centimeter cube has a mass of only 2.7 grams. The density of water and air Liquids and gases are matter and have density. The density of water is about one gram per cubic centimeter . The density of air is lower, of course â much lower. The air in your classroom has a density of about 0.001 grams per cubic centimeter.
