What are metals?
Metals are elements that are typically hard, shiny, and good conductors of heat and electricity.
What are non-metals?
Non-metals are elements that lack the properties of metals, are usually brittle in solid form, and are poor conductors of heat and electricity.
Give an example of a metal.
Iron (Fe) is an example of a metal.
Give an example of a non-metal.
Sulfur (S) is an example of a non-metal.
True or False: All metals are solid at room temperature.
False, mercury (Hg) is a metal that is liquid at room temperature.
What property is used to distinguish metals from non-metals in terms of conductivity?
Metals are good conductors of electricity, while non-metals are poor conductors.
Fill in the blank: Metals tend to lose ______ in chemical reactions.
electrons
Fill in the blank: Non-metals tend to gain ______ in chemical reactions.
electrons
Which group of elements is known for being the most reactive non-metals?
Halogens are known for being the most reactive non-metals.
What is the general trend in reactivity for metals?
Reactivity of metals increases as you move down a group in the periodic table.
What is the general trend in reactivity for non-metals?
Reactivity of non-metals decreases as you move down a group in the periodic table.
True or False: All metals can be hammered into thin sheets.
True, this property is known as malleability.
What term describes the ability of metals to be drawn into wires?
Ductility
Which metal is known for its corrosion resistance?
Gold (Au) is known for its corrosion resistance.
What is the chemical symbol for sodium?
Na
What is the chemical symbol for oxygen?
O
Which type of bond is formed between metals and non-metals?
Ionic bond
What is the oxidation state of metals in most compounds?
Metals typically have a positive oxidation state.
What is an example of a metalloid?
Silicon (Si) is an example of a metalloid.
True or False: Non-metals can exist in all three states of matter.
True, non-metals can exist as solids, liquids, and gases.
What is the main characteristic of noble gases?
Noble gases are inert and do not readily react with other elements.
What is a common use of metals in everyday life?
Metals are commonly used in construction and manufacturing.
What is the main use of non-metals like nitrogen?
Nitrogen is primarily used in fertilizers.
Fill in the blank: Metals typically have ______ melting and boiling points.
high
