False, they are aggregations of ions in a crystal lattice

Silver dichromate
200
Iron(III) Oxide
FE2O3
200
Ionic compounds are both malleable and ductile.
True or False? Explain your answer.
False, they are brittle and would break if hammered
200
Which of the following is a binary compound? Name it.
NaOH
KCl
AgNO3
Zn(IO3)2
What is potassium chloride?
200
The type of elements tend to form anions and why?
What is non-metals? They are electron takers (receivers) with high electronegativity values.

Potassium permanganate
300
Tin Sulfite
Sn(SO3)2
300
All ionic compounds are soluble in water.
True or False? Explain your answer.
False, but most are highly soluble
300
What type of charge do cations possess and what types of elements tend to form them?
What is positive charge, metals?
300
Name the atom most likely form a ionic bond with Cl- in a 1:1 ratio
I
Fr
F
Xe
What is Francium?
400
CuSO4
Copper (II) sulfate
400
Mercury dihydrogen phosphate
HgH2PO4
400
Ionic compounds conduct electricity in the solid state
True or False? Explain your answer.
False, they only conduct electricity in the molten or aqueous state because the ions must be free to move in order to conduct a current
400
Which of the following is an empirical formula? Name it and explain why.
Sn2(SO3)4
AgCl
Zn2O2
What is silver chloride? Because it is the only one listed in the lowest whole number ration (the other two are molecular formulas or could be simplified)
400
This element can form multiple ions -- name the ions.
Zn
Na
Pt
Cs
What are platinum (II) and platinum (IV)?
500
Pb(C2H3O2)2
Lead (II) acetate
500
Magnesium Oxalate
MgC2O4

What is electronegativity? What is the most electronegative element? What is the least electronegative element?
Electronegativity is the ability of an atom to attract electrons toward itsself. Fluorine is the most electronegative element and francium is the least electronegative element.
500
Which of the following are polyatomic ions? Name them.
OH-
Na+
C2H3O2-
Cl-
What are hydroxide and acetate?
500
Explain what happens when ionic compounds dissociate in water.
What is: the crystal lattice dissolves/loses its structure as the cations and anions that comprise it separate and move freely in the solution?
