• Magnesium is a metal, it is actually an
  alkali-earth metal!
• Little Mag, has 12 protons, 12 neutrons, and 12
  electrons
• Mg

4
Properties

• Melting point 650 degrees Celsius
• Boiling point 1090 degrees Celsius
• Specific heat 1.05 kJ
• Density at 239K 1.738g/cm3

5
Chemical Properties

• 2 valence electrons
• Oxidation number 2
• Reactivity highly reactive
• Magnesium nitrate, Magnesium methoxide and
  Magnesium fluoride, are compounds of magnesium

6
Positives and negatives

• Magnesium, when burned, produces a bright light,
  so if you are trapped in a dark cave, and have
  magnesium to burn, you will have light, however,
  it burns really fast, so the light will not last
  long.
• Low amounts of magnesium in blood can cause
  health issues.

Beryllium

• Chemical Description
• The Valence number is 2
• Ion is positive 2
• Maximum oxidation number is 2
• Minimum oxidation number is 0
• There is no reaction between Beryllium and water
  or steam (including when at a red hot).

23
Beryllium

• Beryllium has positive attributes such as being
  used in nuclear reactor to absorb neutrons. It is
  being used in radiation windows for x-ray tubes.
  The element also is under research to find out if
  it could be used as a new mental to construct
  aircrafts because of it being so light-weight.
• The negative attributes include the fact that
• beryllium and its salts are poisonous and
• carcinogenic.

24
Calcium

• Parent
• The first discoverer of this element were the
  Romans
• Birth Place and Date
• Sir Humphry Davy was the first to declare Calcium
  as a metal in 1808 A.D.
• Gender
• Calcium is a metal under the group of Alkaline
  Earth Metals.

25
Calcium

• Number of Protons 20
• Number of Electrons 20
• Density 1.55 g/cm3
• Melting Point 842 C

Calcium

• Chemical Description
• The Valence Number is 2
• Ion is positive 2
• Oxidation States is 2
• Calcium can react with water to make calcium
  Hydroxide.

27
Calcium

• Calcium has positive attributes such as getting
  rid of sulfur, carbon, and oxygen from alloys. It
  is also an important aspect to the water we
  drink. Without this element there would not be
  the removal of arsenic and animal waste in
  drinking water.
• A negative attribute to calcium would be if
  someone has taken in a lot of calcium more than
  needed, remaining calcium can be created into
  kidney stones.
