Studied by 3 peopledistance from the nucleus
the principal quantum number tells us
m(l)
quantum number that tells us the particular orbital within a sublevel
isoelectronic
same amount of electrons means the pair is
5
how many valance electrons are there in the energy level of P
3
two electrons in the same orbital must have the same NUMBER of quantum numbers in common
gamma rays
which has the longest wavelength
thompson
who discovered electrons with a cathode ray tube
ruthford
who fist suggested the nuclear model of the atom
equal energy
what does denegerate mean
frequency
is directly proportional to the energy of a photon
photon
value increases as the energy of light increases
blue
shortest wavelength
pauli exclusion principal
most quantum numbers shared between two electrons in the same atom is 3
hund’s rule
helps chemist determine the number of paired and unpaired electrons in an atom
4
n=3 m(l)
4s1 3d10
what is copper’s valence conficuration
lower
radio waves have BLaNK frequency
longer
radio waves have BLaNK wavelengths than visible light
p-block
which periodic table block has the least amount of metals
decreases electron electron repulsion
the most probable reason several elements violate the Aufbau principal is because of
lambda
wavelength
nu
frequency
C
speed of light
E
energy
h (6.63x10-34 J`xsec)
planks constant
2
how many sublevels are in the 2nd sublevel
electrons in the outermost shell of an atom
what is a valence electron
the (l) quantum number
number of sublevels present (quantum number)
2
number of electrons that can occupy any orbital
electrons decrease by a definite quantity
if an atom releases energy in the form of light
electrons leave their ground state and move to a higher energy level
when an atom absorbs energy
m(l)
3rd quantum number
f sublevel
contains 4 different dumbbells
blue
highest energy
