What you need to study for chapter 2 test :
The only notes you can use are the index cards on
table 2.4 (common cations) -textbook page 60 and
table 2.5 (common anions) - textbook page 62
As promised here are the topics -
1. Atomic structure
-determine the number of protons, neutrons and electrons if the mass number of the element is given
-isotopes notation : hyphenated and subscript/superscript
-atomic mass/weight calculation if the atomic masses and percent abundance of isotopes are given
-definitions for alpha, beta and gamma particles
2. Periodic table
-classification of elements
3. Empirical and molecular formula
-definition
-calculations if percent mass of moles are given
4. Ionic compounds
-predicting ionic charge
-oxidation number
5. Molecular compounds
-predicting bond type based on element location in the periodic table
-write chemical formulas for ionic /molecular compounds if the name of the compound is given
-name ionic/molecular compounds if the chemical formula is given
6. Organic compounds
-naming alkanes, alkenes and alkynes
Don't forget to bring your CALCULATORS !!!!!
Have a great Sunday !
