AP Chemistry - Photoelectron Spectroscopy (PES)

______ has more protons, so its peaks would be closer to the y-axis on a PES graph than ______'s peaks. (Chlorine and Sulfur separate answers with ; )

Chlorine; Sulfur

I'm an element with 6 peaks on a PES graph. In my last subshell I have one electron. What am I? (use element symbol)

K

What is PES an acronym for?

Photoelectron Spectroscopy

What can be determined from a PES graph?

The element, the electron configuration, the number of electrons, the binding energy of electrons

The more binding energy an element has could have been caused by an increase in protons or...

an increase in effective nuclear charge (Zeff)

On a PES graph, the x-axis represents ____________ and the y-axis can represent ______________ ________________ or _____________ ____ ___________________. The peaks represent _________________ and the further the peaks are from the origin, then the further the electrons are from the ________________. (separate answers with ; )

binding energy; signal intensity; number of electrons; subshells; nucleus

The more protons an element has results in a...

higher binding energy

Electrons further away from the y-axis would have _____________ (greater or less) binding energy, which would make them ______________ (easier/harder) to remove.

less; easier

The more electron-electron repulsion an element has results in a...

lower binding energy

If an element has more electrons, there would be an increase in...

signal intensity
