Chemistry Models of particulate nature

How do electrons return to lower levels?

by releasing energy

How do we refer to electrons which are at a higher energy and farther from the nucleus?

in an excited state

what do the lines in line emission spectra represent?

a specific energy value suggesting that electrons can only possess a limited choice of allowed energies

what is it called when lines move towards eachother in the line emission spectra?

convergence

what does the an electron reaching maximum amount of energy mean ( last lines on line emission spectra)

electron reaches ionisation energy

Transition from n = ∞ to n = 3

infared region with low energy

Transition from n = ∞ to n = 2

visible region with medium energy

Transition from n = ∞ to n = 1

ultraviolet region with high energy

emission spectra rule to remeber

always has to be emission, meaning to goes downwards
