questions.
1)No complete sentences…just give the
answer

1.
Atomic Mass on the Periodic
Table represents a “weighted
average” of the mass of all the
naturally occurring ISOTOPES of
each element. (based on mass
& abundance of each isotope.)
Number of PROTONS (Unique to
each element)
Number of ELECTRONS (IF Atom
is NEUTRAL)
2.
3.
Sum of the particles in the
nucleus
Represents total count of
protons and neutrons
Positively charged because
neutrons have no charge and
protons are positive
7. Most Common Isotope
Have you noticed that some elements on the
periodic table have decimal points?
This is because the Atomic Mass Number is the
weighted AVERAGE of all the known isotopes.
In order to know the MOST COMMON
ISOTOPE… round the Atomic Mass Number to
the nearest whole number.
Write the MOST COMMON ISOTOPE by giving
the element symbol +rounded number.
Examples: C 12 or Rb 86

1. This Pattern works for the “TALL”
columns.
2. Since there can not be any more than 8
valence electrons….it’s a quick clue.
3. This pattern does not work for the
“SHORT” columns.
