Name to Formula
calcium chloride
CaCl2
AgCl
silver chloride
What's the name of Fe2+?
iron (II)
Are ionic compounds malleable or brittle?
Brittle (when hit, they break instead of forming a flat sheet)
Which type of element can form the cation in ionic compounds?
Metals
aluminum oxide
Al2O3
MgSO4
magnesium sulfate
What's the name of P3-?
phosphide
Why do ionic compounds have a high melting point?
A lot of energy is required to overcome the attraction between cations and anions in the crystal lattice
What is an ionic bond?
Electrostatic attraction between opposite charges
lead (IV) oxide
PbO2
NH4NO3
ammonium nitrate
What ion does Ca form?
Ca2+
A substance can conduct electricity as a solid. Is it an ionic compound?
No
Through electron transfer from metal TO nonmetal
zinc sulfide
ZnS
FeBr2
iron (II) bromide
What's the only polyatomic cation that we've learned?
ammonium (NH4+)
Why can ionic compounds only conduct electricity either when melted or when dissolved in water?
Because you need FREELY moving ions to conduct electricity
Why do cations lose and anions gain electrons anyway???
To become stable (like noble gases)
Cr2S3
KMnO4
potassium permanganate
Which two groups of metals never need a roman numeral?
1 and 2
A mystery substance has a low melting point, can conduct when dissolved in water, and is brittle. Is it ionic?
No, because melting point is low
True or false: it is possible to have an ionic compound made entirely of nonmetal atoms.
TRUE! (example NH4Cl, ammonium chloride)
