- 3. Multiple Choice
What is an extended structure?
a type of extended structure that is made of many smaller, repeating subunits in a chain; the repeating subunit is a unique molecule
the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up
a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule. An example of this would be salt.
a group of two or more atoms that are held together by chemical bonds; a molecule has a unique composition and structure
- 4. Multiple Choice
What is a crystal?
the connection between atoms in more complex particles
a group of two or more atoms that are held together by chemical bonds; a molecule has a unique composition and structure
a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule
a solid structure whose atoms or molecules are arranged in a repeating, three-dimensional pattern
- 5. Multiple Choice
What is a polymer?
a type of extended structure that is made of many smaller, repeating subunits in a chain; the repeating subunit is a unique molecule
the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up
the specific way in which the bonds and atoms are arranged within the molecules of a substance
a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule
- 6. Multiple Choice
What is the difference between a molecule and a compound?
One is radioactive.
Molecules are made of the same atoms, while compounds are made up of two or more different types of atoms.
They are both made of only a single atom.
One makes you up and the other makes the thing that make you up.
