Groups vs Periods

• periods is a horizontal row of the periodic table and groups are the vertical row of the periodic table

• periods is a vertical row of the periodic table and groups are the vertical row of the periodic table

• periods is a horizontal row of the periodic table and groups are the horizontal row of the periodic table

• periods is a vertical row of the periodic table and groups are the horizontal row of the periodic table

Metals

• are shiny, good conductors of electricity, solid, malleable

• harder metals, used at metals, less reactive

• solid at room temp, some are shiny

• not very shiny, brittle, poor conductors of heat

Transition metals

• shiny, good conductors, solid

• harder metals, used as metals, less reactive

• solid at room temp, some are shiny

• not very shiny, brittle, poor conductors

metalliods

• not very shiny, brittle, poor conductors

• harder metals, used as metals

• solid at room temp, some are shiny

• shiny, solid

non-metals

• harder metals

• not shiny, malleable

• solid at room temp, some are shiny

• not very shiny, brittle, poor conductors of heat

Hydrogen gas

• when a burning splint was put into the test tube a popping noise was made

• when a burning splint was put into the test tube it went out

• when a burning splint was put into the test tube it created carbon dioxide

Carbon dioxide gas

• when a burning splint was put into the test tube it went out

• when a flaming splint was put into the test tube the splint went out because of lack of oxygen

• when a flaming splint was put into the test tube the splint went out because of hydrogen

Mixture vs Pure substance

• Mixtures are made of one or more pure substances. Pure substances only have one type of particle

• Mixtures are pure substances. Pure substances are mixtures

• they are the same

Heterogeneous vs Homogeneous

• you can see the different parts in a heterogeneous mixtures

• you cannot see the different parts in a homogeneous mixtures.

• you cannot see the different parts in a heterogeneous mixtures.

• you can see the different parts in a homogeneous mixtures

Suspension

• heterogenous mixture, large particles, particles settle

• homogenous mixture, large particles, particles settle
