__ELEMENT NAME:__** **Zinc-Zn __ELECTRON CONFIGURATION:__ [Ar] 3d10 4s2 __QUANTUM NUMBERS:__ Principal Number-n=3, Azimuthal Number-l=2, Magnetic Number-m sub l=2, Spin Number-m sub s= -1/2** __ATOMIC MASS:__ 65.39 __NUMBER OF PROTONS:__ 30 __NUMBER OF NEUTRONS:__ 35 __NUMBER OF ELECTRONS:__ 30 __NUMBER OF ISOTOPES:__ 10 __WHAT DOES THE ELEMENT LOOK LIKE?:__ Zinc usually looks like a sheet of aluminum. __FUN FACTS:__ Zinc was discovered by Andreas Marggraf in 1746 in Germany. It originated from the German word "zink." Zinc is the fourth commonly used metal. It is usually used for a protective coating for iron. Zinc is found in the air, soil, water, and is also in food as well. The common uses of zinc include an ingredient for making brass and it is also used to heal wounds and sore eyes. __OTHER INFORMATION:__ Zinc is a bluish-pale gray. It is classified as a transition metal. Zinc is malleable at 100 to 150 degrees Celsius. The shell structure of zinc is 2.8.18.2. Zinc melts at 787.15 degrees Fahrenheit and boils at 1,665 degrees Fahrenheit. Zinc in a sheet form**

__ELECTRON CONFIGURATION:__ [Kr] 5s2 4d10 __QUANTUM NUMBERS:__ Principal Number-n=4, Azimuthal Number-l=2, Magnetic Number-m sub l=2, Spin Number-m sub s= -1/2 __ATOMIC NUMBER:__ 48 __ATOMIC MASS:__ 112.41 __NUMBER OF PROTONS:__ 48 __NUMBER OF NEUTRONS:__ 64 __NUMBER OF ELECTRONS:__ 48 __NUMBER OF ISOTOPES:__ 50 __WHAT DOES THE ELEMENT LOOK LIKE?:__ Cadmium almost looks like a type of iron ore. __FUN FACTS:__ Cadmium was discovered by Fredrich Strohmeyer in 1817. It is also called Quick silver which means "living silver." Cadmium can be cut with a knife and is usually found in zinc, copper, and lead ores. It is commonly used in low friction, fatigue resistant alloys, solders, dental amalgams, nickel cadmium, storage batteries, and much more. __OTHER INFORMATION:__ Cadmium is a soft, bluish-white metallic color. The shell structure is 2.8.18.18.2. Cadmium melts at 320.9 degrees Celsius. It boils at 765 degrees Celsius. The specific gravity is 8.65. Cadmium in an ore form**
 * __ELEMENT NAME:__ Cadmium-Cd

__ELECTRON CONFIGURATION__: [Xe] 4f14 5d10 6s2 __QUANTUM NUMBERS__: Principal Number-n=5, Azimuthal Number-l=2, Magnetic Number-m sub l=2, Spin Number-m sub s= -1/2 __ATOMIC NUMBER__: 80 __ATOMIC MASS__: 200.59 __NUMBER OF PROTONS__: 80 __NUMBER OF NEUTRONS__: 121 __NUMBER OF ELECTRONS__: 80 __NUMBER OF ISOTOPES__: 7 __WHAT DOES THE ELEMENT LOOK LIKE?__: Mercury looks like the liquid you would see in the older thermometers that are not used anymore. __FUN FACTS:__ Mercury was discovered in 1955 by Bernard G. Harvey, Gregory R. Choppin, and Albert Ghiorso. It is commonly used in thermometers, barometers, batteries and pesticides. Mercury can be obviously found in thermometers and on food around the world. It is also poisonous and it can kill people if they consume it. __OTHER INFORMATION:__ Cadmium is a white, dense, metallic element. It melts at 38.87 degrees Celsius and boils at 365.58 degrees Celsius. The specific gravity is 13.546. Cadmium at standard state is a liquid at 298 K. Mercury in a liquid form
