Group 2 Alkaline Earth Metals
Piper, Cameryn, Billy
Beryllium
Atomic Number:4
Atomic Mass: 9 amu
Atomic Symbol: Be
Uses: An alloying agent in producing beryllium copper, which is extensively used for springs, electrical contacts, spot-welding electrodes and non-sparking tools.
Who discovered it? Louis Nicolas Vanquelin
Number of Valence Electrons: 2
Magnesium
Atomic Number:12
Atomic Mass:24 amu
Atomic symbol:Mg
uses: Duralumin and magnalium are alloys of magnesium. The metal is also used in pyrotechnics, especially in incendiary bombs, signals, and flares, and as a fuse for thermite. It is used in photographic flashbulbs and is added to some rocket and missile fuels.
Who discovered it? Joseph Black
Number of Valence Electrons: 2Calcium
atomic number:20
atomic mass:20 amu
symbol: Ca
uses: can be used to remove oxygen, sulfur, and carbon.
who discovered it: humphry davy
number of valence electrons: 2
Strontium
Atomic Number:38
Atomic Mass: 88 amu
Symbol:Sr
Uses: Strontium has found use in producing ferrite magnets and in refining zinc.
Who discovered it? Adair Crawford
Number of Valence Electrons: 2
Barium
Atomic number- 56
Atomic symbol- Ba
Atomic mass- 137
Discovered it- Humphry Davy
Uses- The sulfate, as permanent white is also used in paint, in X-ray diagnostic work, and in glass making.
Number of Valence electrons-2
Radium
Atomic Number:88
Atomic Mass:226 amu
Symbol:Ra
Uses:Radium had been used to make self-luminous paints for watches, aircraft instrument dials and other instrumentation, but has largely been replaced by cobalt-60, a less dangerous radioactive source. A mixture of radium and beryllium will emit neutrons and is used as a neutron source
Who discovered it?Pierre Curie
Number of Valence Electrons:2
