You will Need:1)Pencil, Colored Pencils- All Colors needed2)Power of the Periodic Table– Picked up yesterday

Reminder1)Retakes – oppor tunities - SCHEDULE is on the side Board- Please let me know if and when you plan to retake the test.2) Women in Engineering – Photo shoot release due

# of electrons on outer most shell

1. Atomic Number1. Number of PROTONS (Unique to

each element)2. Number of ELECTRONS (IF Atom

is NEUTRAL)2. Chemical Symbol

1. Abbreviation of element (some from LATIN name)

3. Element Name1. Full name provided below

symbol4. Atomic Mass Number

1. Sum of the particles in the nucleus

2. Represents total count of protons and neutrons

3. Positively charged because neutrons have no charge and protons are positive

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.)

You will need:•Blue•Green•Orange•Yellow•Red•Purple

Color & Label ALKALI METALS BLUE …except for Hydrogen

Isotopes of HydrogenHow do we know that

these are nuclei of

HYDROGEN?

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.element symbol +rounded number.

Examples: C 12 or Rb 86Examples: C 12 or Rb 86

Valence – Periodic Clue for BondingFamily # 1 2 13 14 15 16 17 18

Valence #

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.
