2.2.1 electron structure Flashcards
1
Q
what is an atomic orbital
A
a region within the atom that can hold upto 2 electrons with opposite spins
2
Q
how many electrons can an orbital hold
A
2
3
Q
draw the shape of an s-orbital and what is it called
A
sphere
4
Q
draw the shape of an p-orbital and what is it called
A
propeller/dumb-bell
5
Q
how do you find the number of electrons in the eg-4th shell
A
2n^2
2(4)^2=32
6
Q
what is the rule for “electrons in a box”
A
fill them singly first
7
Q
why would eg-br be classified as a p-block element
A
as its highest energy electron is in the p-subshel
8
Q
what is spin-pairing
A
when 2 electrons occupy one orbital they spin in opposite directions
9
Q
why do we fill electrons up singly first
A
due to electron pair repulsion
