Answer:
Kr has one more electron than br and so, the nuclear charge increase, which means the nuclear attraction between the nucleus and outer most electron will increase and so will be harder to remove the electron from Kr than Br, so Kr has higher 1st ionisation.
Mark me brainliest!

<span>The total number of nodes = n-1.
a) In your case for the 5 d orbital 5 - 1 = 4 nodes.
b) The l quantum number for a d orbital is 2. Therefore you will have 2 angular (planar) nodes.
c) You have 4 nodes, 2 of which are angular. Therefore, you will also have 2 radial nodes.</span>
