Electron Structure Flashcards
What are the 4 subshells called
s,p,d,f
How many orbitals does s have
1 - holds 2 electrons
How many orbitals does p have
3 - holds 6 electrons
How many orbitals does d have
5 - holds 10 electrons
How many orbitals does f have
7 - holds 14 electrons
What are shells numbers also known as
Principle quantum numbers
What shape is s orbital
Sphere
What shape is p orbital
Orbitals are 90 degrees to each other
3 p orbitals in the shape of dumbbells (each dumbell hols 2 electrons)
What happens in the s orbital
Spin pairing - when 2 electrons occupy 1 orbital they spin in opposite directions
electron configuration
1s2, 2s2, 2p6 , 3s2 , 3p6 , 3d6 , 4s2
Why do we fill orbitals singly then pair up
Due to electron repulsion
What does a higher electronegativity mean
More polar
More open to neucleohlilic attack
