Chemical properties of Iron: It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.
Physical Properties of Iron : The melting point of pure iron is 1,536°C (2,797°F) and its boiling point is about 3,000°C (5,400°F). Its density is 7.87 grams per cubic centimeter
Chemical Properties of Tin: Tin is relatively unaffected by both water and oxygen at room temperatures. It does not rust, corrode, or react in any other way.
Physical Properties of Tin: This "white tin" has a melting point of 232°C (450°F), a boiling point of 2,260°C (4,100°F), and a density of 7.31 grams per cubic centimeter.
Chemical Properties of Gold: Gold resists attacks by individual acids, but it can be dissolved by aqua regia.
Physical Properties of Gold: It is one of the least reactive chemical elements.
Chemical Properties of Sulfur: Sulfur burns with a blue flame with formation of sulfur dioxide, which has a suffocating and irritating odor. Sulfur is insoluble in water but soluble in carbon sulfide.
Physical Properties of Sulfur: It melts at 115.21 °C (239.38 °F), boils at 444.6 °C (832.3 °F) and sublimes easily. At 95.2 °C (203.4 °F), below its melting temperature.
Chemical Properties of Phosphorous: White phosphorus is the form that occurs most commonly at room temperatures. It is very reactive. It combines with oxygen so easily that it catches fire.
Physical Properties of Phosphorous: White phosphorus is a waxy, transparent solid. Its melting point is 44.1°C (111°F) and its boiling point is 280°C (536°F).
Chemical properties of Silver: Silver is a chemical element with symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
Physical Properties of Silver: Pure silver is nearly white, lustrous, soft, very ductile,malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid and by hot concentrated sulfuric acid.
Chemical Properties of Titanium: Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.
Physical Properties of Titanium: Pure titanium metal can exist as a dark gray, shiny metal or as a dark gray powder. It has a melting point of 1,677°C (3,051°F) and a boiling point of 3,277°C (5,931°F). Its density is 4.6 grams per cubic centimeter. Titanium metal is brittle when cold and can break apart easily at room temperature.
Chemical Properties of Argon: Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
Physical Properties of Argon: Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth's atmosphere. Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen . This chemically inert element is colorless and odorless in both its liquid and gaseous forms.
Chemical Properties of Neon: Neon glows when a high electrical voltage is passed through it.
Physical Properties of Neon: Neon does not form compounds with other substances and is odorless.
