Quiz Naming Ionic Flashcards
Chemical bond
Attractive force between atoms or ions that binds them together as a unit
Why do bonds form
In order to increase stability
Decrease potential energy
What has the lowest potential energy
Nobel gases
Compound can be either — or —-
Binary (2 elements)
Ternary (more than two )
Ionic bond formation
Electrons transferred from metal to nonmetal
Ionic
Type of structure
Physical state
Crystal Latrice
Solid

Melting point
Solubility in water
Conductivity
High
Yes
Yes (solution or liquid)
Covalent bond formation
Electron are shared between two nonmetals
Covalent
Type of structure
Physical state
True molecules
Liquid or gas
Covalent
Melting point
Solubility
Conductivity
Low
No
No/poor
Ionic or covalent odorous
Covalent
Ions formed from a single atom are known as
Monatomic ions
Ex the -1 or +1
Ionic nomenclature
Stock numbers
On chem helper, ones with Roman numerals
Polyatomic ions / common radicals
Greater number ends in —
Lower ends in—
Greater in ate
Lower in ite
True or false
We can always use the octect rule to predict charges like for transition metals
False, especially for transition metals because they have more than one possible charge
Binary ionic formulas
When monoatomic ions combine (composed of two elements)
What is the formula for percent composition,
Mass of element/ X 100
total mass
Metallic bond formation
Electrons are delocalized among metal atoms (float around)
Metallic bonds
structure
Physical state
Electron sea
Solid except mercury
Metallic bond
melting point
Solubility
Very high
No
Metallic bond
Conductivity
Yes
Metallic bonds other properties
Malleable, ductile, lustrous
In solid water, molecules are called
Waters of hydration
Rule one for hydrated ionic compounds
Just use regular naming for ionic compounds
