Unit 11
Bonding Vocab
| Term | Definition |
|---|---|
| a type of bond that traditionally has a metal and a non-metal bonded together. It also has a great degree of difference between the electron affinities of the atoms and results in one atom giving up their valence electrons to the other atoms. | ionic |
| a bond where the atoms have similar electron affinity so the atoms share their valence electrons | covalent |
| a type of bond between charged or partially charged molecules, such as water that creates surface tension between charged water molecules | hydrogen |
| a bond that has the positive atomic nuclei surrounded by negatively charged electrons that are free to float from one atom to another such as a "sea of electrons" | metallic |
| a positively charged atomic structure | cation |
| a negatively charged atomic structure | anion |
| a way to draw atoms showing only the valence electrons to discover the way in which the atom will bond | lewis structure |
| a geometric arrangement of atoms as a solid | crystal lattis structure |
| A mixture of metals, such as dental fillings | alloy |
| the outer shell of electrons of all atoms is known as the _____________ It is determined by what family the atom belongs to and indicates how the atom will bond with other atoms | valence shell |
| an ion, charged molecule, composed of many atoms | polyatomic ions |
| A bond that shares 2 electrons | single covalent bond |
| A bond that shares 4 electrons | double covalent bond |
| A bond that shares 6 electrons | triple covalent bond |
| Draw CCl 4 Lewis structure | CCl4 lewis structure |
| Draw H2O Lewis Structure | H2O lewis structure |
| Draw HCl Lewis structure | HCL lewis structure |
| Draw F2 Lewis Structure | F2 lewis structure |
| Draw H2S Lewis structure | H2S lewis structure |
| Draw NF3 Lewis structure | NF3 lewis structure |
| Balance the chemical equation on the board | |
| Balance the chemical equation on the board | |
| What is a Hydrocarbon and where do they come from? | A hydrocarbon is a molecule that contains Hydrogen and carbon. They are made from fossil fuels and are named after the number of carbons it possesses. |
| What are these? Propane, butane, methane | Hydrocarbons |
| Determine what type of a bond a hydrocarbon will have. | Do, like the practice sheets |
| If I have this formula am I a hydrocarbon? C6H12O6 | No, that is a sugar molecule. |
| Is this a hydrocarbon? C6H12 | Yes, it is a form of hexane |
| Why are plastics dangerous in the Environment? | Using information from the unit, write a paragraph discussing the evidences from the labs and documentaries we did in class. |
| Explain what polymers are and how they effect formulas. | Using evidence from the labs and lab documents, write a paragraph. |
| Are petrochemicals Hydrocarbons? | Yes |
