Physical Properties Of Atoms Flashcards
What are the physical properties of METALS?
Metals are lustre, malleable, and ductile. They are solid at room temperature, except for mercury (Hg), which is a liquid. They are conductors, which means they are able to transfer heat and electricity.
What are the physical properties of NON-METALS?
Non-metals are dull, and brittle. They are solid or gas at room temperature, except for Bromine (Br), which is a liquid. Non-metals are insulators, which means they cannot transfer heat or electricity.
What are the physical properties of METALLOIDS?
Metalloids are sometimes lustre, are malleable, and ductile. Metalloids are all solid at room temperature. They are semiconductors, which means they can conduct heat and electricity, but not as well as metals, and not as poorly as insulators.
What does brittle mean?
Material that is not malleable or ductile.
What does conductors mean?
Materials that can transfer heat and electricity.
What does ductile mean?
Materials that can be drawn into wire.
What does dull mean?
Materials that are not shiny or lustre.
What does insulators mean?
Materials that cannot conduct heat or electricity.
What does lustre mean?
The shininess of a material.
What does malleable mean?
Materials that can be shaped into thin sheets.
What does semi-conductors mean?
Materials that move heat and electricity only under certain conditions or to a limited degree.
What are the states of matter?
Solids, liquids, and gasses
