equations Flashcards
energy of a quantum
E = hf h = plancks constant
energy of an electron
E = -Rh/ n^2 Rh = Rydberg constant n= quantum #
energy of an e- is _______ proportional to the principle quantum # (n)
directly proportional, bc of the negative sign in the equation, as n increases, gets closer to 0 (thus increasing)
the energy of an e- _________ the further out from the nucleus that is is located
increases
electromagnetic energy
of photons emitted by e- that return to ground state
E=hc/lambda
h= planck's constant c = speed of light = 3*10^8 lambda = wavelength
the energy difference between two shells _________ as the distance from the nucleus increases
decreases
so the energy diff. between n=3 and n=4 is less than the energy diff. between n=1 and n=2
range of possible values for l (azimuthal quantum #)
0 - (n-1)
for any value of n, there will be a max of ______ electrons
2n^2
2 per orbital
draw out e- subshell flow diagram
do it
E = hc/lambda = ?
-Rh*(1/ni^2-1/nf^2)
planck’s constant
6.62610^-34 Js
diatomic elements (7)
H2 N2 O2 F2 Cl2 Br2 I2
dipole moment equation
u= qr
q = charge magnitude r = distance between 2 partial charges
in lewis structure, which atom is the central atom?
the least electronegative
difference between electronic geometry and molecular geometry?
electronic includes bonding and lone pairs around central atom
molecular geometry describes spatial arrangement of only the bonding pairs
