Periodic Table Basics
Metals are located on the __________ of the periodic table.
left
___________ have properties of both metals and nonmetals.
Metalloids
__________ __________ are group 1 on the periodic table. Examples include lithium, potassium, and cesium.
Alkali metals
The group indicated by letter B is very reactive and elements in it lose 2 electrons to be stable. The group is known as:
*** See table ***Alkaline Earth Metals
What group is NOT shown on the periodic table provided for these problems?

Inner Transition Metals
Nonmetals are located on the __________ of the periodic table.
right
Mr. Stephens has an unknown element in a jar. It appears to be gaseous at room temperature. The unknown element is most likely a:
Nonmetal
_________ are group 17 on the periodic table.
Halogens
This group, indicated by letter G, is characterized by low melting and boiling points. It also gains one electron to become stable. The group is:
*** See table
Halogens
Periods on the periodic table are ______________ (horizontal or vertical). Examples of elements in the same period include indium, tin, and antimony.
___________ are good conductors, malleable, shiny, and ductile.
Metals
Element Z is malleable and ductile. It is also a solid at room temperature. Element Z is most likely a _________.
Metal
_________ ________ are group 18 on the periodic table. Examples include helium, neon, and argon.
Noble gases
The most reactive group, it is indicated by letter E here. These elements easily lose 1 electron to become stable.
*** See table
Alkali Metals
Groups (a.k.a. families) on the periodic table are _______________ (horizontal or vertical). Examples of elements in the same group include chlorine, bromine and iodine.
vertical
_________ are poor conductors of heat and electricity. They are also mostly gases and some solids at room temperature.
Nonmetals
Cody finds a shiny element in a chemical storage room without a label. He tests it and finds the element somewhat conducts electricity, but not as well as iron or copper. Also, it is brittle. The mystery element is most likely a:
Metalloid
Cobalt is an example of a __________________ (specific group name).
Transition Metal
Consisting of the most inert (not reactive) elements, this group is indicated by letter C on the periodic table seen above. When electricity is added, elements in this group fluoresce. Think of an OPEN sign. This group is:
