Key Ideas in Chemistry

Which key idea of Chemistry does this illustrate?

• Matter is made up of a variety of chemical elements, each with characteristic properties, and the smallest particle is an atom.

• The structure of matter and its chemical and physical properties are determined by the arrangement of particles and electrostatic interactions between them.

• Energy changes across and within systems usually occur during physical and chemical changes, when there is rearrangement of particles.

• Energy plays a key role in influencing the rate and extent of physical and chemical changes.

• Matter and energy are conserved in all physical and chemical changes.
