Question 36
FThe electrons in an atom orbit the nucleus at set distances from the nucleus.
The Figure shows three of these orbits in an atom. The arrows P, Q and R show an electron moving between orbits.
Figure
a.[1]
Give the letter of the arrow that shows the electron moving when the atom absorbs electromagnetic radiation.
b.[2]
Explain your answer to (a).
c.[2]
Describe what happens when the electron moves along arrow Q.
d.[1]
State the effect on the overall charge of the atom when the electron moves along arrow P.
