CHEMISTRY Physical science

Study of the COMPOSITION, STRUCTURE, PROPERTIES and BEHAVIOR OF MATTER

“THE CENTRAL SCIENCE”

“the ABC of Pharmacy Practice”

MATTER Anything that has mass and volume Made up of particles Exist in 4 fundamental states (S,L,G,P)

Note:Mass- refers to the amount of matter

present in the material.Weight= mass x pull of gravity

STATES OF MATTER

SOLID

LIQUID

GAS

Shape definite indefinite indefinite

Volume definite definite indefinite

IFA strength strongest strong Weakest

Molecular motion vibration gliding CONSTANT RANDOM MOTION

ATOM Basic unit of Matter Gk. “atomos” – indivisible

Proton – (+) charge Neutron- No charge Electron- (-) charge

Found in the NUCLEUS…. Kaya they are collectively called NUCLEONS…. xD

GUYS TAKE NOTE that it is 1,836 times lighter

than a proton; thus, the weight is

negligible, okie?

PROPERTIES OF ELEMENTS Electronegativity – ability of an

element to attract electrons to itself

Electron Affinity – energy gained by an atom when an electron is added to it

Ionization Energy / Ionization Potential – amount of energy required to remove an electron from a neutral atom

PROPERTIES USED TO IDENTIFY SUBSTANCESIntensive/Intrinsic vs. Extensive/Extrinsic

Physical Properties – observed or measured without changing the identity of matter

Ex. MP,BP,Solubility,Ƿ, malleability, ductility

Chemical Properties – describe the change or the reaction a substance undergoes

Ex. Flammability, reactivity, inertness

QUANTUM NUMBERS 1. Principal Quantum Number (n)

- describes the MAIN ELECTRON SHELL and the SIZE of the e- cloud Value: 1,2,3,4….

2. Angular / Azimuthal Quantum Number (l)- describes the SUBSHELL and the SHAPE of the e- cloud Value: 0 up to n-1

QUANTUM NUMBERS 3. Magnetic Quantum Number (Ml)-describes the ORBITAL or ORIENTATION in spaceValues: -l , 0 , l

4. Spin (Ms or s) Values: +1/2 or -1/2

n = 3

l = 0, 1, 2

Ml = -2, -1, 0, 1, 2

RULES / PRINCIPLES1. Pauli’s Exclusion Principle

- No 2 e- can have the same set of quantum numbers

2. Aufbau’s Principle - “Building up” Principle- Electrons are placed first on the subshell with

lowest energy level

3. Hund’s Rule- Electrons are spread singly before pairing up

ELECTRON CONFIGURATION Make your own Mnemonics

Give the Electron Configuration of the following:

Beryllium (At. No. 4)Calcium (At. No. 20)

THE PERIODIC TABLE OF ELEMENTS

Lavoisier – 1st to set up the table (33 elem)

Dobereiner – Triads

Newland – Law of Octaves

Meyer & Mendeleev – 1st Periodic Law; properties are periodic functions of atomic wt.

Moseley – first modern Periodic Table

- 8 elements are grouped before another set of 8 elements

NOTE: 118 elements, 18 groups/families, 7 periods or series

PERIODIC TRENDS Atomic Radius

½ the distance between 2 nuclei Right to left increases Top to bottom increases

Electronegativity Ability to attract electrons Left to right increases Going up increases

Ionization energy or potential Ability to remove an electron from a positively charged atom Left to right increases Going up increases

Electron affinity Property to accept an electron Right to left increases Top to bottom increases

CHEMICAL BONDING - Forces that hold atoms together- All elements try to achieve the configuration of the NOBLE GASES

* OCTET RULE – atoms become stable when the valence e- will complement fully the valence shell

TYPES OF CHEMICAL BONDING:

1. Complete e- transfer (a.k.a. IONIC BOND)- bond formed by a metal and a non-metal- ELECTROSTATIC BOND

2. Sharing of e- (a.k.a. COVALENT BOND)- 2 nonpolar (similar atoms) equal e- sharing- 2 polar (dissimilar atoms) unequal e- sharing

I.M.F. (INTERMOLECULAR FORCES OF ATTRACTION)1. Dipole-Dipole (Keesom Forces)

2. Dipole-Induced Dipole (Debye Forces)

3. London Forces (Dispersion) (Van der Waals)

4. H-bond (Hydrogen attached to a highly electronegative atom)

Conditions at S.T.P.

Conditions:

GAS LAWS BOYLE’S LAW —Volume is inversely proportional to pressure 

CHARLES’ LAW— Volume is directly proportional to temperature (Kelvin) 

AVOGADRO’S LAW —Volume is directly proportional to moles  

DALTON’S LAW OF PARTIAL PRESSURE- States that the pressure exerted by a mixture of gases is the sum of the partial pressures that each gas in the mixture exert individually

GAS LAWS IDEAL GAS LAW

GRAHAM’S LAW —The rate of the effusion of two gases (and diffusion) are inversely proportional to the square roots of their densities providing the temperature and pressure are the same for the two gases. DIFFUSION=gradual mixing of molecules of one gas with the molecules of

another gas by virtue of their kinetic properties  EFFUSION=passage of a gas under pressure through a small opening

SOLUTIONS Solute + Solvent Factors affecting solubility:

1. Nature of Solute and Solvent2. Temperature: Temp = Solubility (MOST OF THE TIME)

3. Pressure: Pressure = Solubility of gas in Liquid – (HENRY’S LAW)

EXCEPTIONS: Exothermic: Inc in Temp = Dec Solubility Solution of gas in liquid: Inc in Temp = Dec

Solubility

REMEMBER that GAS and Ca(OH)2 are the most common substances that dissolve in COLD TEMPERATURE

CHEMICAL THERMODYNAMICS Thermodynamic System- part of the universe

isolated from the rest by a boundary

“Surrounding” = Everything outside

TYPE OF SYSTEM ALLOWS EXCHANGE OF

Open (Non-conservative)

Matter & Energy

Closed (Conservative)

Energy ONLY

Isolated (Adiabatic) No matter, No energy

LAW OF THERMODYNAMICS 1st Law of Thermodynamics - Heat and work are forms of

energy transfer. Energy is invariably conserved, however the internal energy of a closed system may change as heat is transferred into or out of the system or work is done on or by the system.

2nd Law of Thermodynamics - An isolated system, if not already in its state of thermodynamic equilibrium, spontaneously evolves towards it. Thermodynamic equilibrium has the greatest entropy among the states accessible to the system.

3rd Law of Thermodynamics - The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance at absolute zero temperature is zero

WHAT YOU NEED TO REMEMBER:

“Conservation of Energy”

“Energy of the Universe is CONSTANT”

KEYWORD 1: ENTROPY

KEYWORD 2: GIBBS FREE ENERGY

GFE- expendable amt of Energy

ΔG(-) = SPONTANEOUSΔG(+) = NON-SPONTANEOUS

ΔG(0) = Equilibrium

KEYWORDS: ENTROPY OF A

PURE CRYSTALLINE IS EQUAL TO

ZERO

1st LAW 2nd LAW 3rd LAW

CHEMICAL EQUILIBRIUM- It is a STATE at which the amount of Reactant and

Products present are CONSTANT

LE CHATELIER’S PRINCIPLE- if a system is subjected to stress, the

system will adjust to relieve the stress

Stress: Concentration Pressure and Volume Temperature Catalyst – causes NO SHIFT in Equilibrium (PLS. REMEMBER )

IONIC EQUILIBRIUM Electrolytes dissociates into ions

Acids and BasesCheckpoint: Can you FILL IN THE BLANKS?
