Simple Molecules and Extended Structures

Front

What is the chemical formula for caffeine?

C8H10N4O2

Front

What is an example of an extended structure?

Back

An extended structure (crystal lattice)

Front

What is an extended structure?

Back

A structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms (like Carbon) or a molecule (like propane or butane).

Front

Why are oxygen molecules (O2) different than ozone molecules (O3)?

Back

They have different structures, different amounts of atoms, and different chemical formulas.

Front

What holds molecules together?

Back

Chemical bonds/attractive forces.

Front

What is a molecule?

Back

A group of two or more atoms that are held together by chemical bonds.

Front

What is a diatomic molecule?

Back

A molecule that consists of two atoms, which can be of the same or different elements.

Front

What is a crystal lattice?

Back

A three-dimensional arrangement of atoms or molecules in a repeating pattern.

Front

What is the difference between a simple molecule and an extended structure?

Back

A simple molecule consists of a fixed number of atoms, while an extended structure has a repeating pattern of atoms.

Front

What is the significance of chemical formulas?

Back

They represent the types and numbers of atoms in a molecule.
