Knowledge
Students know:
- The periodic table orders elements horizontally by the number of protons in the atom's nucleus and places those with similar chemical properties in columns.
- The repeating patterns of the periodic table reflect patterns of outer electron states.
Skills
Students are able to:
- Identify and describe of the main group elements.
- Describe how the number of protons determines an elements place on the periodic table.
- Predict patterns of behavior of an element based on its position on the Periodic Table.
- Predict number and charges of stable ions formed from atoms in a compound.
- Determine the number and type of bonds formed.
- Predict numbers of protons, neutrons, and electrons based on periodic table information.
Understanding
Students understand that:
- Students will understand how to propose an argument and defend their claim on electromagnetic radiation safety.
- Non-ionizing radiation, such as those emitted in electronics.cannot cause immediate damage, but does interact with the body to potentially cause indirect damage, following long-term exposure.
- Ionizing radiation, such as X-rays and gamma rays, can be hazardous.
