Alkali Metals
Alkali metals are in what group on the periodic table?
Group 1A
Alkaline-earth metals are in what group on the periodic table?
Group 2A
Where are the transition metals located on the periodic table?
The "valley" of the table and the two rows below.
Reduction
This is the largest family of elements.
Transition Metals
Why aren't alkali metals ever found in their pure form?
They have a high reactivity and need to bond for stability, so they're always found in compounds or ores.
These two alkaline-earth metals are among the most common metals on earth.
Calcium and Magnesium
What are the two rows below the periodic table called?
The inner-transition metals
What element is sometimes used during reduction, usually if just using hot air isn't enough to heat the ore.
Carbon
This is what happens when certain metals react with water.
Alkali metals combine with elements in group 7A to form these.
Salts
This metal is commonly used in space travel.
Beryllium
What is the only metal liquid at room temperature?
Mercury
What happens to the electrons during a metallic bond?
They combine and surround all the bonded atoms in a sea of electrons. They are shared equally.
This is the process of coating a metal with another metal, often to prevent corrosion.
Galvanization or metal-plating
Alkali metals react violently with what?
Water
Name two uses for calcium.
- bone and dental health
- making plaster or mortar
- shell development in oysters, clams, and snails
- softening water
This is when a metal is magnetic, but only in the presence of a magnetic field.
Paramagnetic
This is a substance that consists of multiple different metals combined.
Metal Alloy
These are the two elements pennies are made of.
Copper and Zinc
Alkali metals react with elements in group 7A to form _____.
Salts
Name two uses for Magnesium.
- used in antacids and medicine.
- used in space vehicles.
- used in fireworks.
This is when a metal is magnetic even if the magnetic field has been removed.
Ferromagnetic
This metal is often added to metal alloys to increase strength.
Nickel
This metal is ideally used for galvanizing other metals.
Zinc
