Weight= mass x pull of gravity SOLID LIQUID GAS Shape definite indefinite indefinite Volume definite definite indefinite IFA strength strongest strong Weakest Molecular motion vibration gliding CONSTANT RANDOM MOTION 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? Pure chemical substance Contains only 1 type of atom Currently, there are 118 elements Atomic number = # of protons = # of electrons Mass number = # of protons + # of neutrons Atomic Number: ________ Mass Number: _____ Protons: _____ Electrons: ____ Neutrons: ____ Charge: ____ Isotope – Same no. of protons (so same element), but diff. no. of neutrons Isotone Isobar- same number of Neutrons same mass number Dividing line between solution and homogenous mixture True Solution Homogenous mixture Colloid 4 Properties of COLLOIDS: always remember (T-BAC) Tyndall effect Brownian movement Adsorption (ooooops…. hindi po Absorption) Charged electrically O, Si, Al 1 produced artificially – Tc Rarest Element – At Liquid at room Temp – Hg / Br 3 most Abundant Elements – st Hi future RPhs, Please REVIEW THE CHEMICAL SYMBOLS in THE PTE METALS NON-METALS Good conductors of heat and electricity Poor conductors Form BASIC oxides Form ACIDIC oxides Lustrous, Ductile, Malleable Dull & Brittle if Solid High Density Low Density High Melting point Low Melting point Tends to lose e- Tends to accept e- NOTE: Metallic Property – Capability of an element to lose an e- @FutureRphs PLEASE TAKE NOTE #brotip #brotip 1.

Silicon, Germanium, Polonium, Sb (Antimony), Arsenic, Telurium, Boron -Don’t forget it- 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 Intensive/Intrinsic vs. Extensive/Extrinsic Physical Properties – observed or measured without changing the identity of matter Ex.

Reduction-Oxidation Rxn (REDOX) Review: GEROA and LEORA - Separation of particles based on e- charge Let’s make ELECTROCHEM simple e- e- ee- e- e- e- e- e- eee- e- ANODE CATHODE -Oxidation -POSITIVE electrode -Reduction -NEGATIVE electrode Democritus – “Atomos” Dalton – “Billiard Ball Model” Thomson – “Raisin Bread Model” / electron Rutherford – “Gold Foil Expt” / proton in the nucleus James Chadwick – Neutron Bohr – “Planetary Model” Schrodinger – “Quantum Mechanic Model” / 3D model 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 3. Magnetic Quantum Number (Ml) -describes the ORBITAL or ORIENTATION in space Values: -l , 0 , l 4. Spin (Ms or s) Values: +1/2 or -1/2 n=3 n=4 l = 0, 1, 2 l= Ml = -2, -1, 0, 1, 2 Ml = 1. 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 Make Give your own Mnemonics the Electron Configuration of the following: Beryllium (At. No. 4) Calcium (At. No. 20) Lavoisier – 1st to set up the table (33 elem) Dobereiner – Triads Newland – Law of Octaves - 8 elements are grouped before another set of 8 elements Meyer & Mendeleev – 1st Periodic Law; properties are periodic functions of atomic wt. Moseley – first modern Periodic Table NOTE: 118 elements, 18 groups/families, 7 periods or series Atomic Radius Electronegativity Ability to attract electrons Left to right increases Going up increases Ionization energy or potential ½ the distance between 2 nuclei Right to left increases Top to bottom increases 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 - 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 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: 1 atm / 760 mmHg (torr) 0 deg. Celsius / 273 K NOTE: At STP, 1 mole of a substance occupies You can forget your Birthday, BUT NEVER EVER EVER EVER FORGET Conditions at S.T.P. 22.4 L 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 pressures that each gas in the mixture exert individually partial 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 Solute + Solvent Factors affecting solubility: 1. Nature of Solute and Solvent 2. Temperature: Temp = Solubility (MOST OF THE TIME) 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 3. Pressure: Pressure = Solubility of gas in Liquid – (HENRY’S LAW) Thermodynamic System- part of the universe isolated from the rest by a boundary “Surrounding” = Everything outside TYPE OF SYSTEM ALLOWS EXCHANGE OF Open (Nonconservative) Matter & Energy Closed (Conservative) Energy ONLY Isolated (Adiabatic) No matter, No energy 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 1st LAW “Conservation of Energy” “Energy of the Universe is CONSTANT” 2nd LAW KEYWORD 1: ENTROPY KEYWORD 2: GIBBS FREE ENERGY GFE- expendable amt of Energy ΔG(-) = SPONTANEOUS ΔG(+) = NON-SPONTANEOUS ΔG(0) = Equilibrium 3rd LAW KEYWORDS: ENTROPY OF A PURE CRYSTALLINE IS EQUAL TO ZERO - 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.
