ORGANIZATION OF THE PERIODIC TABLE

An element is lustrous, malleable, ductile, and conducts heat and electricity.  It must be a

• metal
• nonmetal
• metalloid
• other

What do we know about the group highlighted in the picture?

• They are very reactive metals--alkali metals
• They are fairly reactive metals--alkaline earth metals
• They are reactive nonmetals--halogens
• They are unreactive gases--noble gases

What do we know about the group highlighted in blue?

• They are extremely reactive metals--the alkali metals
• They are fairly reactive metals--alkaline earth metals
• They are reactive nonmetals--the halogens
• They are unreactive gases--the noble gases

What do we know about the group highlighted in green?

• They are extremely reactive metals--alkali metals
• They are fairly reactive metals--alkaline earth metals

In the modern periodic table, elements are arranged by:

• atomic mass
• atomic number
• valence electrons
• number of isotopes

Atoms with similar properties are most likely located...

• in the same period.
• in the same group.
• in different periods.
• to the right and left of each other.

• period 2.
• group 2.
• group 17.
