2020-2021 Objectives of Chemical Bonding
General Understanding of When Atoms Come Together
1) Be able to identify an element as metal, non-metal or semi-metals from its location on the Periodic Table.
2) Be able to explain what a covalent bond is, what elements would create one, the name of the most common compound you get from this bond and the base unit(s) (or particle).
3) Be able to explain what a "ionic bond" (does not really exist) is, what elements would create one, the name of the compound you get from this "bond", and the base unit(s) (or particle).
4) Be able to explain what a "metallic bond" is, what elements would create one and the main components of the metallic bond.
5) Be able to tell if there is a covalent bond, "ionic bond" or metallic bond between two elements.
Already been tested on this as of Feb 2021
Metallic Bond
Covalent Bonding - General Information
Covalent Bonding - Lewis Dot Structures
5. Write Lewis Dot Structures for Elements and all species that contain covalent bonds (molecular cpds or polyatomic ions). This includes resonance structures and central atoms that can exceeding the Rule of Eight conditions.
1. Determine the Lewis Dot Structure (LDS) for covalent bonding species (e.g. molecular cpds and polyatomic ions). This includes 1)total number of valence electrons, 2)number and types of bonds and 3)number of lone pairs on central atom.
2. From the Lewis Dot Structure, give the geometry (and bond angle) and hybridization of covalent bonding species. You must memorize the geometry and bond angles from VsperTable . For hybridization, define what a covalent bond is with respect to the orbitals, and explain how hybridization justify the exceeding the Rule of Eight (only central atoms in 3rd energy level or higher can work since have d subenergy level).
Covalent Bonding - VSPER (Molecular Geometry)
10. Need to be able to determine which of three type of bonds (single, double and triple bond) has the longest/shortest bond length and/or bond energy and reason why.( 2019-2020 Honors student NEED TO Know)
