Orbitals and subshells

Orbital

region or space around the nucleus that can hold up to 2 electrons with opposite spins

p orbitals contain how many electrons?

6

d orbitals contain how many electrons?

10

f orbitals contain how many electrons?

14

shape of s orbital?

spherical

shape of p orbital

figure of 8

Why do orbitals fill singularly first

so that there’s less repulsion

What are the exceptions?

Chromium and copper atoms only fill 4s subshell to 1 and then adds the extra electron to 3d

What do the blocks in the periodic table show

which orbital the valence electrons are in

What to remember when writing ion electron configuration?

4s orbitals fills and then empties before 3d orbitals
