Intro to the Periodic Table

Mendeleev ordered his periodic table in order of 

Has the mass of One AMU

The number of NEUTRONS is the Atomic Mass - the Atomic Number

Has a positive (+) charge

The number in the top of a box of the periodic table

The Alkaline Earth Metals, Group (Family) 2, have how many Valance Electrons

The group that does not form bonds

AMU stands for

Has a negative (-) electromagnetic charge

What type of elements have properties opposite of the metals

Has a neutral electromagnetic charge 

Another name for the elements in the same column (top to bottom)

The center of an atom

If an atom has an (atomic # of 36) and an (atomic mass of 70), how many PROTONS does it have

The number that is the protrons plus the AVERAGE number of neutrons found in a particular atom

Number of protons in a nucleus

What type of element make up the largest portion of the periodic table

Metals in group one are called

control what the element will bond with

Another name for a row (from left to right) on the periodic table.

If an atom has an (atomic # of 20) and an (atomic mass of 41), How Many NEUTRONS does it have

The Atomic #     IS   the number of PROTONS in the NUCLEUS!

Determines what the element IS 

the relationship of the elements in the same row / period.
