Magnesium
Magnesium was
discovered by Joseph
Black in the United
Kingdom in 1755.
Magnesium has an atomic
number 12. It's symbol is Mg.
The electron arrangement of
magnesium is 2,8,2. This
means that magnesium has 2
valence electrons. Magnesium is in period 2, group three
of the periodic table. Magnesium's density is 1.738g/
mL.
Magnesium can be cast, forged, and welded. It is used in incendiary
bombs and is used in signals and flares.
Magnesium is only 2/3 as
dense as aluminum. Early structural uses of magnesium
alloys were in aircraft fuselages, engine parts, and wheels.

Titanium
Titanium was
discovered by William
Gregor in 1791 in the
United Kingdom.
Titanium has an atomic number of 22. It's atomic mass is 48.
Titanium's chemical symbol is Ti. Titanium rests on the
periodic table at period 4, group 4. The electron arrangement
of titanium is 2,8,10,2. Titanium has 2 valence electrons.
Titanium is used in
aerospace industry,
building, implants for
surgery, and sports
equipment. Titanium is
also used in offshore
rigs and in several
ship's propellers.
