Benchmark Specific Resources:
I can …
1. Identify elements with similar valance electrons as having similar chemical properties.
2. Identify elements likely to form cations, likely to form anions and likely to form no ions.
3. Predict the ionic forms of elements from groups 1, 2, 13, 15, 16, and 17 and identify the ions formed as metallic cations or non-metallic anions.
4. Identify compounds as ionic or molecular (covalent) based on ionic compounds being the combination of metals with nonmetals or polyatomic ions and molecules being the combination of two or more nonmetals.
5. Identify how electrons interact in covalent bonds, polar covalent bonds, ionic bonds, and metallic bonds.
6. Identify metals and non-metals from electron configuration or position on the periodic table.
7. Construct Lewis electron dot structures and use the structures to predict if the bond formed would be ionic or molecular.
8. Use the octet rule to predict the bond order and chemical formulas for simple binary compounds.
9. Identify that polar bonds result from unequal sharing of electrons between bonded atoms.
10. Predict physical properties of a chemical such as solubility in polar and nonpolar solvents, crystallinity, melting point and boiling point and based on understanding the general properties of ionic, polar and molecular compounds.
11. Recognize that carbon atoms can bond to each other in chains, rings and branching networks to form a great variety of molecular structures including the large molecules essential to life.
