Which block of the periodic table are the MOST reactive metals found?
the s-block
Which block are the Alkali Metals located in?
the s-block
Which elements are Alkali Metals?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium*
What are the properties of Alkali Metals?
1. Shiny, solid, malleable, ductile, good conductors
2. Low density and low melting point
3. Soft
4. Oxidizes (tarnishes) easily
5. Reacts easily with water or air
Which group in the periodic table has both low density and low melting point?
Alkali Metals (located in the s-block)
How many valence electrons do Alkali Metals possess?
One
Do Alkali Metals have a high or low ionization energy?
Low (easily lose only valence electron to form a 1 plus charge)
Why are Alkali Metals the most reactive metals?
They lose their only valence electron to form cations.
What do all Alkaline Metals react with?
Halogens
Which reactive, s-block elements are most abundant?
Sodium and Potassium
How are s-block elements found?
As compounds in nature (seawater, mineral deposits)
Which group is group 2A in the s-block?
Alkaline Earth Metals
Which elements make up the Alkaline Earth Metals?
Be, Mg, Ca, Sr, Ba, Ra*
What are the properties of the Alkaline Earth Metals?
1. Shiny, solid, malleable, ductile, good conductors.
2. Higher densities and melting points than alkaline metals
3. react w/ water
4. Oxidizes easily
5. Not as reactive as alkali metals
6. Form 2 plus cations
What are two differences between Alkali Metals and Alkaline Earth Metals?
1. Alkaline Earth Metals have higher densities and melting points than Alkali Metals
2. Not as reactive as Alkali Metals
What is an alloy?
1.When one metal is added to another metal.

2. A homogenous mixture of metals
Which block are transition metals found in?
the d-block
Where do transition metals play an important role?
In living organisms and strong, structurally useful materials.
Which d-block elements are most abundant?
Fe and Ti
Do the properties of transition metals vary from familiy to family?
Yes
What are the characteristic densities and melting points of d-block (transition metals)
high density, high melting point.
Which block do coinage metals belong to?
the d-block
Which elements are coinage metals?
Cu, Au, Ag
Which block do the inner transition metals belong to?
the f-block
How do Lanthanides differ from Alkaline Earth Metals?
Less reactive than Alkaline Earth Metals.
What are the properties of Lanthanides?
1. Soft, silvery
2. Oxidizes readily in air
3. Not good structural material
4. Used in production of TV screens
Which f-block group is radioactive?
the ACTINIDES
Which elements in the Actinide group occur in nature?
Thorium and Uranium
What is a property of the actinide group?
All elements after Uranium are artificial
Which f-block element is used in nuclear power plants?
Uranium
