A-level atomic structure Flashcards
whats the principal quantum number
describes the energy of an electron and the most probable distance of the electron from the nucleus
whats the formula for calculating the maximum number of electrons allowed in each main energy level
2n^2
whats the prinicple quantum number of the third shell
3
whats the prinicple quantum number of the first shell
1
what does n stand for in the formula 2n^2
principal quantum number
whats an atomic orbital
an atomic orbital is a region around the nucleus that can hold up to two electrons with opposite spins
whats an electron
a cloud of negative charge
what does the atomic orbital show you
the atomic orbital shows you the 95% probability of where an electron will exist.
what type of spins are there
up spin and down spin
what shape is the negative charge cloud
it has the shape of the orbital occupied by the electron
what are the 4 letters of the different typres of electronic orbitals
s,p,d,f
what shape is the s orbital
spherical
what shape is the p orbital
dumbell
do all electron shells contain an s orbital
YES
does every electron shell contain a p orbital
No
