 Increasing radii: Cations are.... smaller than parent atoms. Increasing radii: Anions are... larger than their parent atoms. Increasing radii: For ions carrying the same charge... size increases as you go down a column in the periodic table Ionization Energy the minimum energy required to remove an electron from the ground state of the isolated gaseous atom or ion. {The greater the ionization energy, the more difficult it is to remove an electron.) neutralization reactions Acid + Base --> H20 + salt in net ioonic equations, separate aq into ions, and keep everything else together, if H20 is there, just put L the more protons, the more acidic name the 7 strong acids (H+) - these completely dissociate in H20 Hydrochloric, hydrobromic,hydroiodic,sulfuric(h2s04), Chloric (HClO3), Perchloric HClO4) name the strong bases alkali metals, calcium Molarity is one way to measure the concentration of a solution…formula is moles of solute over volume of solution in liters calculate the concentration (M)…. MaVa=MbVb how many moles are formed in neutralization…. take given volume x molarity/concentration of base Dilution problems : how would you prepare… solution diluted to a volume of… M1V1 = M2V2 Calculating Concentration of a solute in a solution… MaVa = MbVb Solution problems: how many ml are needed to neutralize?? since 1 mole acid is needed to neutralize 1 mole : MaVa=MbVb Molarity can be solved these ways molarity, dilution, titration Titration is: the technique in which one can calculate the concentration of a solute in a solution.. Molarity of acid x volume of acid = molarity of base x volume of base Endergonic greater than zero, entering endothermic absorbs heat (endo =in) exothermic heat exits , reaction gives off heat, therefore change in Heat is negative heat energy in joules (absorbed) is calculated by Heat Energy = mass x change in Temp x Specific Heat specific heat is calculated by heat transferred / mass x temperature change All members that have very similar chemical properties are all in the same column Order for atomic radius can be calculated just by looking at atomic number (for example, Na is 11) Ionization energies refer to chart change in heat (delta H) sum of negative electron affinity wants to be negative Most metallic can be found where on the periodic table? farthest to the Left Non metals are…. Acidic/Basic? non metals are always acidic Metals are…. Acidic/Basic metals are always basic
