Parent: Kyle Preston

The Birth

• First Born by Sir Humphry Davy

• Born in 1808

Physical Description

• Magnesium is a metal, it is actually an alkali-earth metal!

• Little Mag, has 12 protons, 12 neutrons, and 12 electrons

• Mg:

Properties

• Melting point: 650 degrees Celsius

• Boiling point: 1090 degrees Celsius

• Specific heat: 1.05 kJ

• Density: at 239K – 1.738g/cm^3

Chemical Properties

• 2 valence electrons

• Oxidation number – 2

• Reactivity – highly reactive

• Magnesium nitrate, Magnesium methoxide and Magnesium fluoride, are compounds of magnesium

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• Parent

– The French Chemist Louis-Nicholas Vauquelin

• Birth place– Beryllium was discovered

in 1797 found in emeralds located in the mountains of California and in France

• Gender– Beryllium is a metal

found under the category of Alkaline Earth Metals.

Beryllium

• Physical Properties– Number of Protons: 4– Number of Electrons: 4– Density : 1.848 g/cm– Melting Point 1287 °C– Boiling Point 2470 °C

Specific Heat Capacity 1.82 J

– Thermal Conductivity 2.00 W/cm K

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).

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.

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.

Calcium

• Number of Protons: 20• Number of Electrons:

20• Density: 1.55 g/cm3• Melting Point: 842 °C• Boiling Point: 1484 °C• Specific Heat Capacity

is 0.650 J/g°C• Thermal Conductivity

2.00 W/cm K

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.

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.
