1. Today in Science
You will Need:
1)Pencil/Pen, Colored Pencils, Highlighters
or Markers
2)Log #2 – Update – Managers in charge
today; PROGRESS NOTICES TOMORROW
3)Power Notes – Atomic Structure– 2 pages
4 sides – Picked up on Friday and Monday

2. Reminders
Test #1 Retakes – Available only until Thur.
of this week
Please check your grades for Accuracy-
Printing Progress Notices this Afternoon
Power Notes- Atomic Structure
1)Colored Pencils, Highlighters or Markers-
must highlight notes
2)Review and Reflect on ALL PAGES

3. All atoms found on the • Neutral – same # of protons(+) and
Periodic Table are # of electrons(-)
Isotope • Atoms of the same element with
same number of protons and
different number of neutrons.

4. Atomic MASS • On the Periodic Table represents a
weighted average of the mass of all
naturally occurring isotopes of each
element. (based on mass and
abundance of each isotope).
• When atoms gain or lose electrons
IONS
they become charged. (number of
protons (+) and electrons (-)
particles are NOT EQUAL)
