Understand the general properties of metals in chemistry, which include physical and chemical characteristics.
Recall that metals are typically good conductors of electricity due to the presence of free-moving electrons in their structure.
Recognize that metals are usually malleable and ductile, meaning they can be shaped without breaking, so they are not generally brittle.
Note that metals tend to have relatively high melting points compared to nonmetals, so low melting points are not a common characteristic.
Remember that metals tend to lose electrons to form cations, not gain electrons to form anions.
