Can use to find electron configuration #
The isotope that is most similar to the atomic mass is the most abundant
Electronegativity trends
Important for bonding #
How the covelent bonds work
Can be used to determine the bond length
can determine the bond strength
Thermodynamics
How much energy is required to break the bonds
Helps Predicts Reactions #
Thermodynamics
Derminers if its exo or endothermic
Like Dissolves Like
Can be used to determine sponteniety
Determines what type of bond is formed
Can be used to calculate the equilibrium constant
Calculate how much energy is released when a certain number of moles of substance is burned
#
Can be used to calculate the empirical formulas
Can be used to calculate Molarity #
Molarity is Used in Acid Base
Solutions #
Electrochemistry
Used to Calculate moles in a reaction #
Couolums Law
The greater the radius the more soluble
Solubility
If it is easily soluble then it is spontaneous
And it is product favored
How easily an atom is willing to accept an electron #
This determines the properties of the substance
Its Solubility
Melting and Boiling Point
Used to calculate the enthalpy and spontaneity
Determines if the reaction is spontanous
Determines if the reaction is product or reactant favored #
Predicitng a reaction allows you determine if the entropy of a reaction.
Knowing the entropy of the reaction you can calcuate delta G
Helps you find the Element quickly #
Lets you know what energy level the element is on
Helps you identify the element quickly
Elements in the same groups have similar properites #
Properties tend to get more extreme as you move down a period
#
Helps you know the number of valence electrons in the element
#
Elements from the same group share the same number of valence electrons
#
Molarity is used in beers law
Molarity is important for absorbance calculations
can help you determine what type of bond is formed between two molecules
Can help you determine which bonds are broken and formed
#
Helps with enthalpy calculations
Can be applied to solutions
know solubility
If it was polar it would dissolve in polar substances
If it is non polar it would dissolve in nonpolar substances
Determines the electron geometry
Determines the molecular Geometry
Helps you know the bond angles of the molecule #
Structure of the molecule is affected by lone pairs
Structure would determine what type of intramolecular forces are present
#
This could be used to compare which of two elements may have a stronger attraction
Determine which has a higher boiling point
Determine which has a lower freezing point
Calculating the molarity
This can be used to calculate the equilibrium constant
Use the Concentrations of Products over Reactants to calculate Keq
Can Also be used to calculate Q
Determines where the equilibrium would shift to produce more of product or reactant depending on K and Q values
Can be used to calculate order
Use Molarity to determine the order of the reaction
Use the order of reaction and concentrations to calculate the rate constant
We can then use the rate constant to calculate the half life of a particular substance
Knowing the rate constant we could also determine what order the reaction is when given the graph
This can be used to determine if the element is in the ground state or excited state
If an element is in its excited state the electron configuration
would be a half filled d and s orbital for a transition metal
Can help you know the properites of the bond formed #
If there is a large electronegativity difference then it may be an ionic
If the electronegativity difference is large but not large enough to completely remove the electron then it may be a dipole covalent
Could be a evenly shared covalent bond if the electronegativities of the two atoms are similar or equal
Balancing Equations
Stoichometry
Finding Percent Composition
Can be used to find limiting reagent
can be used to find what is in excess
can be used to calculate how much of a product is produced
importnat conept for combustion analysis
helps determine the molecular formula #
helps determine the empirical formula #
Can be used in gravimetric analysis
Helps determine which compound was initially reacted and precipitated using the percent composition
Helps balance redox reactions #
Helps determine how many moles of electrons were transferred
#
This is key to doing electrochemistry porblems
Knowing moles of electrons allows you to calculate time the reaction was run
#
How many g of the initial substance were present
How many electrons were transferred as a whole
Use to figure out electron configurations #
Number of subshells
Used to figure out number of moles #
