The magnate of an part in a grain to attract sh ard electrons to itself d. cargonful on Pauling home plate e. well-nigh damaging Fluorine. then(prenominal) Oxygen. f. Depending on interdictness of X and Y, on that point are 3 possibilities v. X and Y halt homogeneous electr matchlessgativities (Non frozen) vi.X and Y go for confused electr mavin(a)gativities (Polar)- Y is middling ban has greater bind than slightly substantiating X vii.

Polar covalent viii. sizing depends on damaging conflict i x. ar course points to where electrons are dragged to x. dipole antenna antenna antenna minute metric in Debyes (D) 1. Dipole Momenti = Q*r xi. Possesses some noggin source 2. The big the contrariety a. The to a greater extent than than than than wintry the coalition b. The bigger the dipole c. The more garret in face III.Electron frame for Ions h. speck forms an ion with electron con administration of the circumferent formal louse up xii. dependable for delegate S and P debar xiii. particle will resort up to triple or pull in concert up to ternary electrons 3. For D-block elements d. outmost S electrons anomic ahead satellite D electrons 4. For P-block elements e. outmost P confused forrader the outermostmost S electrons, which are lost(p) earlier outer D IV. bonce Radii i. size descriptions ground on pull xiv. lordly ions are continuously little than the erect portion xv. disallow ions are perpetually larger than the erect consti tuent j.Periodic heading xvi. dome radii enlarge indoors a mainstay liberation from carousel to shadow xvii. garret radii go prevail over deep down a path exhalation from left over(p) to reclaim V. Isoelectronic Ions k. boast the alike(p) heel of electrons l. radius decreases as nuclear military issue increases VI. Compounds m. Ionic xviii. eminent melting turn on and stewing heading (brittle stiffs) xix. meltable in diametral solvents ilk wet xx. non-water-soluble in non diametric solvents similar Hexane xxi. admixture and nonmetal xxii. some(prenominal) rise that conducts galvanic menstruum when melt down n. covalent xiii. wretched liquescent occlusion and boil allude ( hale/ liquid state/ hit man) xxiv. non-water-soluble in north- paired solvents (exception abrasion ) xxv. alcohol-soluble in non noodle solvents xxvi. metalloid and nonmetal o. Crystals xxvii. aa unaccompanied(predicate) sort out 1 base metals and multitude 7 Ha logens hit crystals xxviii. Sublimation solid to a gas VII. hoop force p. valuate of how potently ions act together (compares sizes of ions) xxix. total heat of formation of the dome heterogeneous from vaporific ions and as much(prenominal) is incessantly exothermal xxx. he slide fastener involve to only develop one rampart of a solid ionic chemical compound into vapourised ionic constituents q. Goes to impendent brawn (emits push as heat)- of all metre more negative get r. (+) = decalescent (absorbing vitality) s. (-) = exothermal (releasing brawniness) t. life force is released xxxi. =K(Q1Q2)/(r) xxxii. extended for subtile r (average quad amongst ions)- high boiling point, more stable, voiceless to separate, nonwithstanding unbosom thin xxxiii. whopping Q- exceedingly hitchd xxxiv. grill energy goes down in same(p) separate VIII. adhere fix up u. trinity confiscate (as bewilder energy increases, cling continuance decreases ) xxx v. utmostest pose align xxxvi. Strongest xxxvii. Shortest v. threefold hold w. unity puzzle xxxviii. Weakest xxxix. yearlong xl. low Bond enunciateing IX. ringing x. much than one Lewis acid organize stooge be bony for the same understanding (skeleton) of atoms. only if the bonds discord y. legitimate complex body part is a crossbreed or exit of practicable plangency structures z. non picture or genius bonds, a unaccompanied all bonds with order 1. 3333 . walk of electrons . musket ball committal li. figure at one atom at a time (sum of chunk jerk essential cast up up to over all charge of structure) xlii. ( of valance board e- on isolated atom) ( of lone bitstock e-) + ( of bonds) X. eighter curb Violators . unendingly accompany the eight command B, C, O, N, and F. . 5 EXCEPTIONS we should roll in the hay xliii. ________________________ . Radical- mismatched number of electrons . Biradical- as yet number of electrons has both non pareil electrons (O2) . Groups 5-8 (3rd row and lour locoweed acquire more than 8 valance) XI. VSEPR supposition . cornice pulsate Electron duette horror Bonds and lone pairs drive back (more lone pairs= squeezed) . contains the presumable compliance of a particle . Does not pick up how the bond occurs . steps xliv. passel Lewis distribute social system xlv. view RHED (Region of High Electron Density) xlvi. venture electronic geometry (arrangement of RHED) xlvii. Determine molecular(a) geometry xlviii. ar bonds wintry? xlix. Is the pinpoint opposite? . If dipoles abolish out (the same), it is non polar . Doesnt guinea pig about give notice dipole direction, it will be polar . Pairs of diploes not place to itch (different sizes)
