Molecule Study Guide Questions

Question 1

Glucose and fructose both have an atomic composition C6H12O6 but they are different molecules. What is most likely the major difference between them?

Answer 1

The major difference is most likely that the structure is different between glucose and fructose.

Question 2

List 2 differences between crystals and polymers?

Answer 2

Crystals are a structure of atoms or molecules but polymers are only structures of molecules. Crystals are in a 3D pattern but polymers are in a repeating chain pattern.

Question 3

C3H4 has how many elements? Atoms?

Answer 3

• 2 elements
• 7 Atoms

Question 4

What is an element?

Answer 4

One type of atom represented by 1 square on the periodic table.

Question 5

What is an atom?

Answer 5

The smallest unit of matter that has the properties of an element.

Question 6

What is a molecule?

Answer 6

A molecule is two more atoms bonded together.

Question 7

When making molecule models, what do the beads represent? The sticks?

Answer 7

The beads of the atoms and the sticks represent the chemical bonds.

Question 8

Can you have two different crystals that are made up of the same atom? Give an example. How is it the same? How is it different?

Answer 8

Yes, you can. Because the structure of the atoms could be different, causing the property of the elements change. The diamond and graphite are both made out of carbon. Both diamond and graphite are made out of carbon Adams, which makes them the same. Graphite has a repeating powder for the structure of the atoms which diamonds don’t have.
