What is an element?
• Basically, if it is listed anywhere on the
periodic table (of the elements) it is an
element.
• If it is on the left side it is a metal element, if it
is on the right side it is a NONmetal element.
(Hydrogen is the ONLY nonmetal to the left of
the stairstep line.)
• Let’s look . . .
Where are the metal elements?
Left of the Stair-step line!
Where are the nonmetals?
To the Right of the stair step line, and Hydrogen!
Where are the metalloids?
Along the stair
step line.
These elements
have properties
of both metals
and nonmetals.
The center elements on the table are called the transition
metals. Many of them have more than 1 way they will give
away electrons, so they change, or transition, ion charges.
The charge these metals use are given by a roman numeral in
the name. (Iron (II) chloride)
The Rare Earth Metals are radioactive and form
the bottom 2 rows, also called the Lanthanide
and Actinide Series.
So, I can tell if it’s a metal or not, what
else?
• Each column on the table is a group or family
of elements that have similar chemical
properties.
• They form the same types of compounds, in
the same ratio.
• They have the SAME NUMBER OF OUTER
SHELL (valence) electrons.
• Lets look . . .
Group # 18 is the family called Noble Gases – each
one has 8 outer shell electrons (full shell) so they
don’t form compounds.
Group #1 is called the Alkalai metals, they
have 1 valence electron, and will form +1
ions. The are Alkalai because they form the
strongest (highest pH) bases.
Group #2 is called the Alkalai Earth Metals and they
have 2 valence electrons, which they will give away to
form +2 ions.
Group #17 are the Halogens, they all have 7 electrons
in their valence shell, and want to have 1 more when
they form compounds. They all become -1 ions when
they can.
For each group, they form compounds the same
way, for example. . .
• Beryllium forms a compound with Cl in the
ratio of 1:2 or BeCl2
• Since Mg and Ca are in the same family or
group, they will form the same type of
compounds in the same ratio.
• MgCl2 and CaCl2
• This is what is meant when they have
“similar chemical properties”
Each square also tells us information about
each element.
• The 1 or 2 letters that
represent the element
are its symbol.
• The number at the top
of the square is the
atomic number.
• The numbers at the
bottom of the square is
the average atomic
mass.

volume. Particles flow easily; they spread far
apart and fill up the space of a container
