You will Need: 1)Pencil, Colored Pencils- All Colors needed 2)Power of the Periodic Table– Picked up yesterday
Reminder 1) Retakes – oppor tunities SCHEDULE is on the side BoardPlease let me know if and when you plan to retake the test. 2) Women in Engineering – Photo shoot release due
Proton Electron - + + Nucleus 0 Neutron
Valence - Proton Electron # of electrons on outer most shell + + Nucleus 0 Neutron
Atomic Number 1. 1. 2. Chemical Symbol 2. 1. Abbreviation of element (some from LATIN name) Element Name 3. 1. Full name provided below symbol Atomic Mass Number 4. 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 Number of PROTONS (Unique to each element) Number of ELECTRONS (IF Atom is NEUTRAL) 1. 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

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
Valence – Periodic Clue for Bonding Family # 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.
