Introduction to the Periodic Table
Dmitri Mendeleev made the _________________________________
What is the PERIODIC TABLE?
oShows all known ________________ in the ______________________.
oOrganizes the elements by ______________________________________.
How else is it organized??
Mendeleev arranged the elements by _______________________________
But he noticed there was something still not quite right about it
Now, the periodic table is arranged by ______________________________!
How do you read the PERIODIC TABLE?
What is the ATOMIC NUMBER?
oThe number of _______________ found in the __________________ of an atom
Also…
If it is a _____________ atom (not an ION) the atomic number will also tell you the
number of ___________________
What is the SYMBOL?
oAn abbreviation of the __________________________.
What is the ATOMIC WEIGHT?
oThe number of __________________________________ in the nucleus of an atom.
How do I find the number of protons, electrons, and neutrons in an element using
the periodic table?
# of PROTONS = _____________________________________
# of ELECTRONS = _________________________________ (neutral)
# of _________________ = ATOMIC WEIGHT - ATOMIC NUMBER
Parts of the Periodic Table
The periodic table is divided into rows and columns…
–GROUPS – ___________________ across periodic table; there are ________
groups
–PERIODS – _______________ up and down the periodic table; there are _____
groups
Special Group Names
Group 1: ______________________________
Group 2: ______________________________
Group 3-12: ____________________________
Group 17: ______________________________
Group 18: ______________________________

How else is it organized?
Metals are found to the __________ of the _________________ in the periodic
table
Non-metals are found to the __________________ of the ________________
Right on the staircase are elements having both metallic and non-metallic
properties and these are called _________________________ (semi-metals)
Properties of…
METALS
