The Periodic Table
Where elements come together
Periodic Table—an organized list of all known elements that are arranged according to their properties.
The 1st person to organize elements was Dmitri Mendeleev in the 1800s.
Mendeleev organized the elements by their atomic mass and left spaces for unknown elements.
The Periodic Table
Mendeleev’s table was mostly correct, but it
is more accurate to organize elements in order of increasing atomic number.
The Modern Periodic Table
Protons = Atomic Number
Atoms get their identity and properties due to the number of protons they have
change the #p+ change the element Electrons = Number of protons
For neutral atoms, ions are different Neutrons = Atomic Mass – Atomic
Number Atoms of the same element can have
different masses. These are called isotopes. The difference in mass is due to more or less neutrons
Teach the Teacher: If you had to be
a teacher what subject would you want to teach? What subject do you think would be the hardest to teach?
Review: Is CO2 a compound or element, or mixture?

Flash Card
On the Front Write:
Atomic Number
On the Back Write:
Top number, tells the number of protons and electrons
Chemical Symbols (Scientist Texting)
Abbreviations for chemicals Punctuation is KEY
Capital Letters big, little letters small Spacing
Elements ALWAYS Start with a capital letter Symbols can be 1,2 or 3 letters First letter is capitalized and 2nd & 3rd are
lowercase
Example of Messing up Chemical Symbol
CO doesn’t equal Co CO = Carbon
monoxide
Co = Cobalt
Periods—horizontal
rows of elements on the periodic table. Periods are
numbered 1-7 Elements increase
by one proton as you move from left to right across a period.
Periods
Groups
Groups (or families)—vertical columns on the periodic table.
They are numbered 1-18. Elements in each group have
similar properties.
Electrons & The Periodic Table
The periodic table organizes elements based on where their electrons are located.
Electrons (e-)—are located in different energy levels around the nucleus.
Elements in the same group have electrons arranged similarly which gives them similar properties.
Solid, Liquid, or Gas?
Electron Shells
The number of energy levels or electron shells is determined by the period number.
Period 1: 1 electron shell and can hold 2 e-
Period 2: 2 electron shells & can hold 8 e-
Period 3: 3 electron shells & can hold 16 e-
As you move down the periodic table, 1 electron shell is added each time.
The outer electron shell must be full (usually with 8 e-) to be stable.
Teach the teacher questions: If you
could get a gift card to any store in the mall, what store would it be?
Review: List as many elements as you can think of (you can use resources).
Warm-Up 10/26/12
Electron Dot Diagrams
You can show the number of electrons in the outermost electron shell by using an electron dot diagram.
Dot diagrams use valence electrons which are the electrons in the outer electron shell.
Electron Dot Diagram—uses the symbol of the element and dots to represent the valence electrons.
atom or molecule with missing or extra electrons Ions are charged particles (positive or
negative)
charge = #protons - #electrons charge given as a trailing superscript positive ions are cations X+
negative ions are anions X–
