Periodic Table Review
How did Mendeleev Arrange the elements?
By increasing atomic mass
Mendeleev’s pattern repeated after every ____ elements
7
How did Mendeleev predict the properties of missing elements?
By using the pattern he found
States that the properties of elements are periodic functions of their atomic numbers
Periodic Law
Elements in groups 3-12
Transition metals
A column on the periodic table
Group or family
A row on the periodic table
period
What is the name of family 1 on the periodic table?
Alkali Metals
What is the name of family 2 on the periodic table?
Alkaline Earth metals
What word means “Happening at regular intervals (repeating pattern)”
periodic
Elements found to the left of the stairstep line on the periodic table
metals
Elements found to the right of the stairstep line on the periodic table
nonmetals
Elements found along the stairstep line on the periodic table
metalloids
What is the name of family 17 on the periodic table?
halogens
What is the name of family 18 on the periodic table?
Noble Gases
What is the name of family 11 on the periodic table?
Coinage metals
Why are they called the coinage metals?
Because they are all used to make coins/money
List one property of family 1
Explosive, metals, shiny, good conductors of electricity, one electron in outer shell
List one property of family 18
Nonmetals, odorless/colorless, does not react with other elements
List 2 common properties of metals
Shiny, malleable, solids, good conductors of electricity
List 2 common properties of nonmetals
Mostly gases, dull, insulators, not malleable
List 2 properties of metalloids
Shiny/dull, semi-conductors, not malleable, mostly solids
