What is Gas?
This class of elements has low melting and boiling points
What are nonmetals?
This property was used to order Mendeleev's periodic table.
What is Atomic Mass?
The IUPAC numbers system for the groups on the periodic table?
What are numbers 1-18
The group has 2 valence electrons; Be specific with the family name.
What are Alkaline Earth Metals
The transition elements are these types of elements
What are metals?
These elements belong to one class of elements; B, Si, Ge, As, Sb, Te, and Al.
What are metalloids?
Mendeleev used this; the tendency to recur at regular intervals. The elements have properties that re occur at specific intervals.
What is Periodicity? Or periodic trends
This is how Europeans label the periodic table

What is group 1 or alkali metals
A semiconductor are what kind of elements?
What are Metalloids?
Strontium, Magnesium and Calcium all have these in common since they are in the same group on the periodic table.
What are chemical properties?
This scientist rearranges the periodic table to be ordered by atomic number?
Who is Moseley?
This is the cell that contains this information is for each element.
Atomic name
Atomic number

What is a key?
The name of the group that wants to bond with elements in group 6
What is Group 2 or Alkaline Earth metals.
This is how each group of metals, nonmetals and metalloids treat their valence electrons.
What are
Metals: Loosely held
Metalloids: Kind of held but able to move.
Nonmetals: Tightly Held
These Elements can be sorted into representative elements, transition metals, inner transition metals, based on these.
What are electron configurations?
