Ans: 7 electrons
The peaks in a photoelectron spectrum correspond to the binding energy of electrons in a given substance. The lower energy peaks represent the binding energy of the outer or valence electrons whereas the higher energy peaks correspond to that of the inner and core electrons.
The atomic number of bromine is 35. The electron configuration would be:
Br[35] =[ 1s²2s²2p⁶3s²3p⁶3d¹⁰]4s²4p⁵
The valence electron configuration is:
Br[35] = 4s²4p⁵
there are 7 valence electrons, thus the lowest energy peak would be associated with 7 electrons.
Hello,
A physical change describes a change that does physically and does not display “chemical” signs which are signs that indicate a precipitate being formed, change in color, density, or producing gas, etc. “Tearing a piece of paper in half” is a physical change because like I said earlier it doesn’t show any chemical change signs. I hope this helps you out!
