Molecule Study Guide

Question 1

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

Answer 1

The chemical structure is different

Question 2

List 2 differences between crystals and polymers.

Answer 2

Crystals are a structure of atoms or molecules, but polymers are only a structure 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

C3H4 has 2 elements and 7 atoms

Question 4

What is an element?

Answer 4

1 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

2 or more atoms bonded together

Question 7

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

Answer 7

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

Question 8

Can you have 2 different crystals that are made of the same atom? Give an example. How is it the same? How is it different?

Answer 8

Yes, you can. An example is diamonds and graphite. They are the same because they are both made of the atom carbon. They are different because they have different chemical structures.
