The Periodic Table
11/14/11
Catalyst
Take out your periodic table to answer the following
questions:
1. What are the periods and groups on the periodic table?
Periods are the horizontal rows and groups are the vertical
columns.
2. How do you find the number of neutrons in an atom?
How many neutrons are in boron?
Atomic mass – atomic number = number of neutrons. 11 –
5 = 6, there are 6 neutrons in boron
3. Draw a Bohr model (electron rings and nucleus) for
carbon.

Learning Target #4 (Reminder)
LT #4: I can read and understand the
periodic table of elements and explain all
the different sections.

VI. Families and periods
A. The number of rings and number of electrons
on the last ring of any given element
determines it position on the period table.
B. Groups- vertical columns
*Similar chemical properties

C. Each horizontal row on the periodic table is
called a period.
*Not alike, but have the same number of energy
levels

Isotopes =
Atoms of the same element that have
different numbers of neutrons
Example: Carbon-12, Carbon-13, and
Carbon-14
Think-Write-Pair-Share
1. How many neutrons does each one
have? How many protons and electrons?
2. What about for hydrogen? There is
hydrogen-1, hydrogen-2,
and
hydrogen-3.

The Periodic Table
11/16/11
Metals are elements that are good conductors of electric current and heat. They are
also shiny and bendable. The majority of elements in the periodic table are metals.
Physical Properties
Luster (shininess), malleability (can be
hammered into flat sheets), ductility (can
be rolled into long wire), and
conductivity (thermal, transfer heat, and
electrical, transfer electric current)
Chemical Properties
Reactivity – the ease and speed with which a
substance reacts with other substances, Na
reactive and Au unreactive
Corrosion – the gradual wearing away of a
metal due to a chemical reaction, rust
