Metals
Characteristic of metals
What is shiny, good conductor, silver/gray in color, malleable, or ductile?
Characteristic of nonmetals
What is dull, poor conductors, not malleable, and not ductile?
Characteristic of metalloids
What is has properties of both metals and nonmetals?
Evidences of chemical change
What is production of a gas, unexpected color change, change in thermal energy (temperature change), or formation of a precipitate?
Physical properties
What is a characteristic that can be observed without changing the substance?
Example of a metal
What is Iron (Fe), Gold (Au), Copper (Cu), or Aluminum (Al)?
Example of a nonmetal
What is Oxygen (O), Helium (He), Hydrogen (H), or Carbon (C)?
Example of a metalloid
What is Boron (B), Silicon (Si), Germanium (Ge), or Antimony (Sb)?
An example of chemical change from your notes
What is firewood burning, baking soda reacting with vinegar, food becoming moldy, photosynthesis, or cooking?
Chemical properties
What is a characteristic that describes how a substance reacts with other substances?
Malleability
What is the ability to be hammered into thin sheets?
Property of a nonmetal
What is dull, brittle, not ductile, insulator, and low luster?
Common uses of metalloids
What is computer chips, circuit boards, solar cells, detergents, and batteries?
The difference between physical and chemical changes
What is a chemical change results in a new substance, while physical change does not?
Determination of physical properties
What is conducting tests to measure physical characteristics such as color, density, and melting point?
Common uses for metals
What is construction, electronics, cook utensils, or transportation?
Common uses for nonmetals
What is respiration, fertilizers, water treatment, and energy?
Property that's unique to metalloids
What is semiconductors?
Change in thermal energy
What is energy absorption (temperature decrease) or energy release (temperature increase)?
Production of a gas
What is bubbling or fizzing that occurs when mixing two substances?
Metals location on the periodic table
What is to the left of the zig-zag line or staircase?
Nonmetals location on the periodic table
What is to the right of the zig-zag or staircase?
Metalloids location on the periodic table
What is on the zig-zag or staircase?
Production of a percipitate
What is a solid substance formed from a liquid solution?
The difference between physical and chemical properties
What is physical properties can be observed without changing the substance, while chemical properties describe how a substance reacts with others to form new substances?
