electronic structure

when the further the electron shells are away from the nucleus does the energy get higher or lower

higher

what does each shell contain

subshells

what are the kinds of subshells

s p d f

what are the sub shells in shell one

s

what are the sub shells in shell two

s p

what are the sub shells in shell three

s p d

what are the sub shells in shell four

s p d f

what does each sub shell contain

an orbital

what is an orbital

a region where there is a high probability in finding an electron

how many electrons can sub shell s hold

2

how many electrons can sub shell p hold

6

how many electrons can sub shell d hold

10

when filling orbitals what three rules can we use

aufbau principle

pauli exclusion principle

hunds rule

what is aufbau principle

electrons fill the lowest energy first

what is pauli exclusion principle

an orbital con only hold a maximum of two electrons and the two electrons have opposite spins

what is the principle of aufbau order to filling electrons
