Section 1

Question Answer
How to name/write the formula of a monatomic ionwe usually add the suffix -ide to the end, can predict charge based on number of anions and cations
How to name/write the formula of ionic compoundsname the cation before the anion, will have a net charge of 0
How to name/write the formula of covalent moleculesidentify compound name, if it has a charge, put that as prefix(never use mono on first element)
[Acids] -IDEhydro___________ic acid
[Acids] -ATE___________ic acid
[Acids] -ITE___________ous acid
How to name/write the formula of acidsput hydrogen first(always), then the anion name and formula
memorize

Section 2

Question Answer
[Periodic Table] how to predict the ion most likely to form?the charge on a monatomic ion depends on the group; the charage on the ion is writtin as a superscript
[Electron Configuration] how to predict the ion most likely to form?the final "section" of an electron configuration shows the group/period of the ion about to form
How to predict the ratio in an ionic compoutn based on elements position?Ionic formulas can be described using chemical formulas, which represent the ratios of interacting elements tha tare found the ionic solid or salt
memorize

Section 3

Question Answer
[Attraction] Covalent Bond?between two nonmetals
[Attraction] Ionic Bond?between two oppositely charged molecules(metal and nonmetal)
[Attraction] Metallic Bond?between two metals
Describe the model of an ionic compound
Describe the model of a metallic bond
Explain hte electron behavior in a covalent bond
Explain the electron behavior in a ionic bond
What is a chemical bond?the atoms of an element become lower in energy and the bond between the two atoms becomes more stable
memorize

Section 4

Question Answer
Use the model of metals(sea of electrons) to explain the reasons for it's properties
Use the model of Ionic(Crystal Lattice)to explain the reasons for it's properties
Use the model of Covalent(molecules) to explain the reasons for it's properties
Why are Roman Numerals used in writing formulas of ionic compounds?
How to identify the number of valence electrons in an atomthe group number of the element
