Copper (I) chloride
CuCl
What is the only positive polyatomic ion?
Ammonium (NH4+)
What type of charge do cations and anions have?
Cations - positive
Anions - negative
What type of bonds holds ionic compounds together?
Ionic bonds (electrons are transferred)
AlF3
Aluminum fluoride
FeI3
Iron (III) iodide
NaNO3
Sodium nitrate
P2O5
diphosphorus pentoxide
What are the ion charges that form for groups 1, 2, & 13?
Group 1 --> 1+
Group 2 --> 2+
Group 13 --> 3+
What types of bonds hold molecular compounds together?
covalent bonds (electrons are shared)
Ca3N2
Calcium nitride
Lead (IV) oxide
PbO2
Mg(ClO3)2
trinitrogen heptachloride
N3Cl7
What are the ion charges that form for elements in groups 15, 16, and 17?
Group 15 --> 3-
Group 16 --> 2-
Group 17 --> 1-
What types of bonds hold polyatomic ions togther?
covalent bonds (polyatomic ions are groups of nonmetals covalently bonded together that have a charge)
SrO
SnF2
Tin (II) fluoride
Nickel (III) phosphate
NiPO4
NO
Nitrogen monoxide
What two transition metals actually only form one type of ion?
Silver (Ag1+) and Zinc (Zn2+)
What is the octet rule?
When an atom gains, loses, or shares electrons to have 8 total valence electrons
Zinc phosphide
Zn3P2
Au2S
Gold (I) sulfide
FeSO3
Iron (II) sulfite
As3Br8
What is the symbol and charge for an ion that has 16 protons and 18 electrons?
S2-
What group of elements do atoms want to copy in the octet rule?
They want to copy the noble gases and have 8 valence electrons. This is because when an atom has 8 valence electrons it is stable.
AgI
Silver iodide
Titanium (II) oxide
TiO
Ammonium sulfate
(NH4)2SO4
BCl5
Boron pentachloride
What charge do all ionic compounds need to add to?
Zero
Why do atoms of elements want an octet?
This is because when an atom has 8 valence electrons it is stable.
