Manganese metal and its common ions are paramagnetic. Manganese is a silvery-grey hard metal, very brittle and difficult to fuse but easy to oxidize. It is odourless, tasteless, and malleable. Vanadium is a soft, silvery gray, ductile transition metal.Ĭhromium is a steely-grey, lustrous, hard metal with a high melting point. Titanium is a light (low-density) metal that is strong, lustrous, corrosion-resistant and silver in colour. Scandium is a silvery-white metallic transition metal. dissolved in seawater, and as part of minerals.Ĭalcium is a soft grey alkaline earth metal. It occurs in nature only as ionic salts, e.g. Potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water. It is inert under most conditions so forms no confirmed stable compounds. In nature, it can be found as the pure element and as sulfide and sulfate minerals.Ĭhlorine is a pale yellow-green, highly reactive, gas with a strong smell (of bleach) at room temperature.Īrgon is a colourless odourless and non-toxic gas at room temp and pressure. Sulphur is a bright yellow crystalline solid. Elemental phosphorus exists in two forms, white phosphorus and red phosphorus but - due to its high reactivity, phosphorus is never found as a free element in nature. It is found in dusts, sands, and forms of silicon dioxide (silica) or silicates. Silicon rarely occurs in free element form in nature. The free metal burns with a distinctive brilliant white light. It is non-magnetic, non-sparking and insoluble in alcohol. It is a soft, durable, lightweight, ductile and malleable metal whose appearance ranges from silvery to dull gray. The free metal burns with a distinctive brilliant white light.Īluminium is found naturally only combined with other elements as it is highly reactive. Magnesium is found naturally only combined with other elements as it is highly reactive. Sodium is a soft, silvery-white, highly reactive "alkali metal" element. Neon is a colourless inert noble gas that glows reddish-orange in discharge tubes and neon lamps. Oxygen occurs as a highly reactive colourless odourless tasteless gas.įluorine is a very reactive poisonous pale-yellowish brown gas. Nitrogen is a colourless odorless tasteless and mostly inert gas at room temperature. The free element beryllium is a steel-gray, strong, lightweight brittle "alkaline earth metal".īoron exists as amorphous boron (a brown powder) and crystalline boron (black, very hard and a poor conductor at room temperature).Ĭarbon exists as graphite, diamond, and amorphous carbon. Lithium is a soft silver-white metal classified as an "alkali metal" element.īeryllium is found naturally only combined with other elements e.g. Helium is a colourless odourless tasteless gas at room temperature. Hydrogen is a colourless gas at room temperature.
