5. Magnesium! Magnesium was first discovered by Joseph Black, in 1755
Magnesium and calcium were thought to be the same element
Magnesium is a Alkaline Earth Metal, and silvery-gray in color.

6. Magnesium!
Magnesium has 12 protons, neutrons, and electrons. Its density is g/cm3.
Magnesium reacts with hydrogen to produce hydrogen gas.
Since it is 2/3 of aluminum's density, alloys of magnesium are used in the construction of cars, missiles, and airplanes.

7. Magnesium!
Magnesium is highly combustible, and when lit produces a brilliant white light. Thus it is often used in fireworks or flares.
Magnesium also has stool softening qualities, and is used in medications such as “Milk of Magnesia” for self-regulation.

8. Calcium aka Ca
“My name is Humphry Davy and I discovered Calcium in 1808!”
“I was born weighing a heavy 1.55 g/cm
Davy tells me when I’m really mad I get so hot, he said my boiling point is 1771 K and then when I calm down I get to 1115 K. 3
“I was born in London”
And learned from my father that I have metal ruining all through me!

9. “Students can draw me in different forms, but I’m still Calcium”
Different Sides
“Students can draw me in different forms, but I’m still Calcium”
“I only have 2 for my valence and oxidation #!”
Other Compounds:
CaO
CaCl
-CaH 2 2
“There’s 20 Protons, Neutrons, and Electrons that create me”
I’m very reactive and like to give my electrons to others 

10. Bad things?? There’s nothing bad about me
I’m Good/Bad
Electrical conductivity: x 10 s cm
Thermal conductivity:
201 W m K 6 -1 -1 -1
“And I’m very important when it comes to Portland and it’s cement!!!”
“I’m good when used to make other metals to make Uranium and Thorium”
Bad things?? There’s nothing bad about me
