Is a cation formed by an electron gain or an electron loss?
Electron loss
100
KI
Potassium Iodide
100
In any ionic compound, how would we name K ion?
Potassium because it is a metal therefore it keeps the same name as the element shown on the periodic table

Write the formula for Tin (II) Chloride
SnCl2
100
Write the formula for Nickel (II) Sulfide
NiS
200
How do positive ions and negative ions form?
An atom gains or loses electrons to achieve a stable electron configuration.
200
AlBr3
Aluminum Bromide
200
Which ion type gets the suffix -ide when ionic compounds are named?
Nonmetals
200
Name FeO
Iron (II) Oxide
200
On an ion, what is the number written as a superscript?
Oxidation number=Charge of an atom
300
Why are all of the elements from group 18 relatively un-reactive, whereas those in group17 are very reactive?
The group 18 elements have complete outer energy levels and do not easily form ions. The group 17 elements are highly reactive because they need only to gain a single electron to form an octet.
300
NaBr
Sodium Bromide
300
When dealing with a metal ion with more than one charge (example: transition metals), how do we name them?
For metal cations with more than one possible charge, the ion charge must be indicated in the ion name. Example: Pb forms Pb+1 and Pb+4, therefore we will name it lead(I) and Lead(IV) respectively.
300
What is the difference between the name of CuCl2 and CuCl?
Roman numerals!
300
In order to form a stable compound, the charge on the anion must _______ the charge on the cation.
Equal to REMEMBER THAT THE CHARGES BALANCE OUT!
400
Explain why potassium does not bond with neon to form a compound.
Neon already has an octet in its outer energy level; it is already stable.
400
NaCl
Sodium Chloride
400
What is the order when naming an ionic compound?
Metal Nonmetal (example: sodium chloride)
400
Write the formula and name for the compound formed between Calcium and Fluorine
CaF2 Calcium Fluoride
400
True or False: Ionic compounds must have a net charge of zero.
True!
500
Why are halogens and alkali metals likely to form ions? Explain your answer.
Halogens need to gain only one electron to have a noble gas electron configuration. Alkali metals need to lose one.
500
AlCl3
Aluminum Chloride
500
How do we name nonmetals that form anions?
We use the element name on the periodic table, but change the endings to -ide

Write the formula for Iron(III) Chloride
FeCl3

Name GaAs
Gallium Arsenide
