Define an element
Chemical matter made up on one kind of atom
Name the three components of an atom
Nucleus of porotns and neutrons, surrounded by a shell orbiting electrons
Which two elements form the largest amount of mass in our known universe?
hydrogen and helium
The sun is composed mostly of one element. Which one?
hydrogen 92%
What process does the sun use to create about 10 elements?
Nuclear fusion
How are most of the natural elements in our universe created?
From previous supernovas (exploding massive stars)
Should we expect to find many new elements in other solar systems and galaxies?
No. We should expect to find the same elements, compounds and minerals everywhere in our universe
What are the four most abundant elements in the earth's crust?
Oxygen
Silicon
Aluminum
Iron
How different should minerals be on other planets, when compared to those on earth?
The formation of space dust and molecules are the same for all galaxies: The "initial" rocks = same
Which "chemical compounds" make up the Earth's crust and mantle?
Rocks and Minerals (which are chemical compounds) make up both the earth's crust and mantle.
Define a mineral.
A natural occurring inorganic solid with specific crystal structure, a specific chemical composition and specific physical properties
Can man-made compunds be considered minerals? Why?
No. It is not a natural occuring substance
Is coal classified by geologists as a mineral? Why?
It is not because it is composed of decayed organic matter.
Why are oil, gas and coal deposits defined by the governments as minerals?
Tax purposes. Minerals are taxed at a higher rate than rocks
Is ice made in a refrigerator a mineral? Why?
Yes. A mineral must be a solid. Therefore Ice and Snow is considered a mineral and water is not.
