Elements Flashcards
Chemical symbol: Li Atomic number: 3 It is an alkali metal and under standard conditions, is the lightest metal and solid element.
Lithium
Chemical symbol: Be Atomic number: 4 It is a relatively rare element found in the core of stars before it fuses and in beryl(emerald and aquamarine)
Beryllium
Chemical symbol: B Atomic number: 5 Produced entirely by cosmic ray spallation and supernovas, the largest mine of this element is in Turkey.
Boron
Chemical symbol: F Atomic number: 9 It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.
Flourine
Chemical symbol: Ne Atomic number: 10 This element is about 2/3 the density of air and has a bright red emission.
Neon
Chemical symbol: Mg Atomic number: 12 A shiny gray solid which bears a close physical resemblance to the other five elements in the Alkaline Earth Metals which all have similar crystal structure
Magnesium
Chemical symbol: P Atomic number: 15 Exists in two major forms, white and red, but because it is highly reactive, it is never found as a free element on Earth.
Phosphorus
Chemical symbol: S Atomic number: 16 It is abundant, multivalent, nonmetallic, bright yellow, and a crystalline solid at room temperature.
Sulfur
Chemical symbol: Cl Atomic number: 17 It is an extremely reactive element that was known since ancient times as common salt.
Chlorine
Chemical symbol: Ar Atomic number: 18 It is the second most abundant gas in the Earth’s atmoshpere, twice as high as water vapor.
Argon
Chemical symbol: Ti Atomic number: 22 A lustrous transition metal with a silver color, low density, and high strength. It is resistant to corrosion in sea water, aqua regia, and chlorine.
Titanium
Chemical symbol: V Atomic number: 23 It is a hard, silvery-grey, ductile, malleable transition metal that is rarely found in nature.
Vanadium
Chemical symbol: Cr Atomic number: 24 It is the first element in group 6 and is the main ingrediant in stainless steel. It is a steely-grey, lustrous, hard and brittle transition metal.
Chromium
Chemical symbol: Mn Atomic number: 25 It is not found as a free element in nature and is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Manganese
Chemical symbol: Co Atomic number: 27 The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal and is only in the Earth’s core as a chemical.
Cobalt
