Properties of Matter for Select Elements
By: Grace Evans
The 3 elements that I am familiar with is oxygen, nickel, and copper. The 3 I am unfamiliar with is carbon, boron, and gallium.
~Oxygen is used to breathe and to help patients in hospitals who can not breathe on their own.
~A interesting fact about oxygen is oxygen forms 21% of earth's atmosphere by volume.
~Nickel is used for making stainless steel and is used for coinage and armor plating. ~ Nickel has an abundance of 85 parts per million in the Earth's crust.
~ Copper is usedf in building construction and electronic product manufacturing.
~ A fact about copper is that it is used to make pennies.
~ Tools and metal cutters have carbon made in them and vegetal carbon is sometimes used as a gas absorbent or bleaching agent.
~Dry ice is solid carbon dioxide
~Boron has been used in rockets as a ignition and is used in pyrotechnics and flares to produce a green color.
~ An interesting fact about boron is that it was discovered in 1808.
~gallium is used for high temperature thermometers and is used to convert electricity into coherent light.
~A fact about gallium is that it is used mostly in electronics.
