Chemistry First Semester Final Review
1. Calculate the relative atomic mass given the relative abundance of isotopes. For example, C-12 is
97%, C-13 is 2%, and C-14 is 1%
2. Be able to rank the bond angles in various molecules. For example- HF, H2O, and NH3
3. Which elements (based on ionization energy and electronegativity) will form an ionic bond?
4. State the shape of a molecule when given its molecular formula. For example, H2S or H3O+
5. Describe or define covalent bonding.
6. Give the correct formula of ionic named compound (don’t forget to recognize polyatomic ion names,
charges, and transitional metals with various charges)
7. Know the intermolecular forces and be able to rank them from lowest to highest. For example, what
kind of intermolecular forces in N2? H2O?
8. Given multiple molecular formulas, be able to rank the most polar to the least polar.
9. Give the electron configuration of a given element.
10. Know the definition of ionic, covalent, and metallic bonding.
11. Know what energy is emitted when electrons fall back down to their ground state when excited.
12. Know the number of protons, neutrons, and electrons in an atom of 14C (or any atom for that matter)
13. Boiling point of various molecules from high to low (which is based on their polarity). For instanceHF, O2, and NH3
14. State the maximum number of orbitals in the third energy level.
15. Identify the number of electrons in an atom or ion.
16. Recognize a correct Lewis structure for a molecule.
17. Be able to make calculations with correct sig figs (+/- rules vs. x/÷)
18. Are compounds with covalent bonds made up of metals, non-metals, or both?
19. Know how the RADIUS, ionization energy, and electronegativity change as you move horizontally
and vertically across the periodic table and explain why.
20. Know what properties decrease down group 17 in the periodic table.
21. State whether an anion or cation has a greater radius that its parent atom and why.
22. What properties decrease going down group 1 (the alkali metals)?
23. Know trends/similarities, differences in physical and chemical properties as you move vertically and
horizontally on the periodic table.
24. Compare and contrast ionic and covalent bonding.
25. Give the correct number of valence electrons (electrons in the highest occupied energy level) of any
element.
26. What is the trend of electronegativity as you move left to right on the periodic table?
27. Be able to correctly identify a correct orbital diagram for a given element.
