Electrons and Bonding Flashcards
1
Q
what is an orbital?
A
can hold a maximum of paired electrons with opposite spins
2
Q
what is a sub-shell?
A
given the letters s, p and d, hold orbitals
3
Q
how do you write long electron configurations?
A
use noble gases eg,
argon= 1s2, 2s2, 2p6, 3s2, 3p6
potassium= [Ar] 4s1
4
Q
why do 3d subshells come after 4s?
A
they are at a higher energy level
5
Q
which groups correspond to which block they’re in/
A
group 1 and 2= s-block
transition elements= d-block
group 3-8 = p-block
weird bottom bit= f-block
