1s, 2s, 2p
2p, 2s, 1s
1s, 1s, 1s
2s, 2p, 2p
Nitrogen shows 3 peaks in its photoelectron spectrum. These 3 peaks correspond to the binding energies of nitrogen's 1s, 2s, and 2p electrons. The relative heights of the 1s, 2s, and 2p peaks in the PES spectrum of nitrogen will be:
1, 1, 1
2, 2, 3
1, 1, 2
2, 2, 5
What is the identity of element Z?
Boron
Carbon
Neon
Magnesium
Which peak shows electrons closest to the nucleus
A
B
C
D
The electrons represented by peak 1 (spectrum 1) require more energy to be ejected because
there are fewer of them
there is a greater nuclear charge
they are closer to the nucleus
there is only one electron so there is no repulsion
