CHEM1405 Test 3

QuestionAnswer
ELECTRONEGATIVITY ___ AS YOU GO UP AND DIAGONALLY ON THE PERIODIC TABLE INCREASES
IONS _______ IN SIZE GOING DOWN COLUMN ON PERIODIC TABLE INCREASE
IE _________ GOING UP PERIODIC TABLE AND TO RIGHT INCREASES
ATOMIC RADIUS _____ GOING DOWN PERIODIC TABLE AND TO LEFT INCREASE
MORE IE = ____ REACTIVE LESS
PAULI EXCLUSION PRINCIPLE ONLY TWO ELECTRONS PER BOX
AUFBRAU PRINCIPLE ELECTRONS OCCUPY LOWEST ENERGY ORBITALS FIRST
SINGLE ELECTRONS OCCUPY DIFFERENT ORBITALS OF THE SAME ENERGY HUNDS RULE
S ORBITAL SHAPE SPHERICAL
P ORBITAL SHAPE 2 LOBES
D ORBITAL SHAPE 4 LOBES
F ORBITAL SHAPE 6 LOBES
RED HAS _______ WAVELENGTH LONGEST
VIOLET HAS _________ FRQUENCY HIGHEST
VIOLET HAS _______ PHOTON ENERGY HIGHEST
SPPED OF LIGHT (C) 3.0x10^8 m/s; C= νλ
PLANCK'S CONSTANT (h) 6.626x10^-34 Jxs
WAVELENGTH (m) LAMBDA- λ
FREQUENCY (1/s) NU- ν
ELECTROMAGNETIC SPECTRUM FROM SHORTEST TO LONGEST WAVELENGTH/HIGHEST TO LOWEST FREQUENCY GAMMA RAY, XRAY, ULTRAVIOLET, VISIBLE (ROYGBIV), INFRARED, MICROWAVE, RADIO
PHOTON ENERGY Ephoton=hC/λ
ENERGY OF PHOTON IS ________ PROPORTIONAL TO FREQUENCY AND _________ PROPORTIONAL TO WAVELENGTH DIRECTLY; INVERSELY
CHANGE IN ENERGY ΔE= Efinal-Einitial
n=6-n=2 ----> GREATEST RELEASE OF ENERGY, HIGHEST FREQ
n=3-n=2 ----> LONGEST WAVELENGTH
DEFICIENCY OF BOHR MODEL ONLY EXPLAINS HYDROGEN
MODERN MODEL OF THE ATOM USES ORBITALS AND PRINCIPAL ENERGY LEVELS; SHOWS PROBABILITY OF WHERE ELECTRONS MOST LIKELY TO BE FOUND (CLOSER DOTS, MORE PROB)
BONDS ARE POLAR AND MOLECULE SHAPE NOT SYMMETRICAL, THEN ITS A _____ MOLECULE POLAR
BONDS ARE NONPOLAR OR SHAPE IS SYMMETRICAL, THEN ITS A _______ MOLECULE NONPOLAR
HYDROGEN TWO ELECTRONS (ONE PAIR)
BORON SIX ELECTRONS (3 PAIRS)
