Describe the general physical state of metals compared to non-metals at room temperature.
Understand the Problem
The question is asking for a comparison between the physical states of metals and non-metals at room temperature. This requires an explanation of the typical characteristics of both categories of elements in terms of their state (solid, liquid, gas) and properties like conductivity and malleability.
Answer
Metals are usually solid, dense, and conductive. Non-metals can be gases, liquids, or solids that aren't dense or conductive.
Metals are generally hard, dense solids with high melting points and good conductivity. Non-metals, however, can be gases, liquids, or softer, colorful solids with lower densities.
Answer for screen readers
Metals are generally hard, dense solids with high melting points and good conductivity. Non-metals, however, can be gases, liquids, or softer, colorful solids with lower densities.
More Information
Mercury is a unique metal as it's liquid at room temperature. Gallium is also noteworthy because it can become liquid on warmer days.
Tips
A common mistake is assuming all non-metals are gases. Some, like sulfur, are solids.
