Electron Energy Levels ch2 Flashcards
colors are result of :
from
electrons emitting energy in the form of light
M it in
emitting=تنبعث
atom emission or released is due to ______________________this called ________
1-relaxation of electron to their most stable or lower energy level and closer to the nucleus
2-ground state
atoms absorbed energy by__________this is called _________ :
1-excitation of electron to higher energy level farther from the nucleus
2-excited state
far thir
farther=بعيد
When electrons move through energy states, they move
in_________
small amount
energy comes in small equal packets so we call energy ____________
Quatlized or photon
The energy level principal are represented by the letter_____ and
is an____________
1-n
2- integer energy level
N tij ir
integer=مستوئ الطاقة الصحيح
describes the energy of an electron and the most probable distance of the electron from the nucleus.
principe quantim number or n
______and_________ of electron cannot be determined at the same time
Location and energy
energy level principal is
where electron may be found
n=1 level is closest to nucleus
sublevels has orbitals defined ad
are spaces that have a high probability of containing an electron
shape of orbital is
sphere
s pheer
sphere
node or nodal plane
is an area of no amplitude.
the zero amplitude means no electron
probability.
why is orbital important?
for bonding of organic
compounds.
These orbitals represent the ________element bonding.
f-block
As mentioned earlier, every orbital can only encompass
a maximum of ________
2 electron
