Power of the Periodic Table.Day 1
Transcript of Power of the Periodic Table.Day 1
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
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.)
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 2 3 4 5 6 7 8
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.
