Transcript of Groups of the Periodic Table of Elements: Mr. Glass

A Periodic table was first organized by a scientist named Dmitri Mendelev
Those "periods" give us the shape we use today
Each box represents one of the elements. It contains important information about each element
Name
Symbol
Atomic Number
Atomic Mass
And some will include other things.
Ions
Isotopes
Electron configuration
Oxidation States
Boiling/Melting Point
O

Atomic Mass
Meaning the same thing kept happening in a cyclical pattern...
like a watch
He noticed that there were "periodic" patterns in the behavior of atoms when listed in order by atomic mass*.
The number of protons
1.66053886 × 10 kg
about the weight of one proton or neutron
But now back to the Periodic Table
The periodic table has groups and periods.
Groups are COLUMNS
Periods are ROWS
Group 1 is called the
ALKALI METALS
Groups
Periods
similar properties
similar size
Group 2
The Transition METALS
Metalloids
The "sort of" metals
The rest are called nonmetals
Another group is named the Halogens
Most elements are metals
They have these properties:
Efficient conduction of heat and electricity
Malleability (they can be hammered into sheets)
Ductility (they can be pulled into wires)
They have luster
HINY!
OOH,
Noble
Gases

Group 18
Transition Metals
OR
Do you notice any patterns in their electron configurations?
Right! They all have only one
Valence Electron
meaning the electrons
on the "outside"
or highest energy level
2 Valence Electrons
Means "Basic" or has the properties of a Base - the opposite of Acid
Their valence electrons don't behave like others'
because of the d-orbitals inside the valence shell.
(NOT C3PO...)
He's made of metal
They like to pair up with Alkalis
And don't spread this around... but they smell!
Like Chlorine...




wait... isn't...
Yup, It's a
Meaning they don't hang around filthy peasants.
(They don't mix with other elements to form compounds)

Our Next Project
We order them by atomic number now
We're going to make our classrooms
very own periodic table.

The metals in the first two groups react with water and acids. They are soft metals and compounds that include them will taste basic, or soapy.
