On Monday, we all shared what we did over break. Then we reviewed some things. We talked about the experiment, where we undid the compounds. We undid the compound CuCl to get separate atoms copper and chloride. We undid the compound by moving electrons around through the system. On Tuesday, we talked about vocabulary. Molecules have can have a positive or negative or neutral charge. Atoms have a neutral charge and when they gain or lose electrons, they become ions and ions have a negative or positive charge. Compounds have a neutral charge. There are two types of compounds we are working with, ionic compounds and molecular compounds. Ionic compounds are compounds of ions that form neutral charges and metals and nonmetals are bonded to together to form the compound. Molecular compounds are nonmetals and nonmetals bonded together. Polyatomicion are compounds with charges. Below and to the left are some examples:
We also went over how to figure out charges of each atom in a compound. Below and to the right is an example:
We went over how to bond an polyatimicion compound with atoms to make them neutral. From example SO4charge-2 is combined with 2 Na because Na has a charge of +1 and if we use two Na with SO4 they will cancel out each other's charges forming a compound of Na2SO4. On Wednesday, I was absent. On Thursday, we did some visual learning with people being electrons and atoms. I tried my best to take notes on the example and they are to the left. We then did then the worksheet and I understood it pretty good and it will come in handy to study from.
On Friday, we took an assessment and I understood most of the questions. I hope I did good on the assessment.
