Answer : 1 electron
Explanation :
atomic number of Ga = 31
electron configuration = [Ar ] 3d10 4s2 4p1
lowest energy peak will be the one with lowest binding energy. for gallium it is 4p electron. so only 1 electron associated with the lowest energy peak of Gallium.
should we expect to see associated with the lowest energy peak in the photolectron electrons
How many bands should we expect to see in the photoelectron spectrum of C2H6?
Predict the color of light that should be associated with the highest energy transition in the visible spectrum of hydrogen? Predict the color of light that should be associated with the lowest energy transition in the visible spectrum of hydrogen. Explain your prediction - why did you choose this one?
Use a molecular orbital energy diagram to explain why we can never expect to see more than a triple bond.
What diagnostic (characteristic) peak(s) do you expect to see with the following functional groups? Indicate the approximate wavenumber, intensity & shape for the peak(s) you expect. Alcohol Carboxylic acid Alkene Aromatic Aldehyde
13. In polyatomic atoms electrons fill the orbitals from the lowest energy to the highest. Write the electron configuration of oxygen. (If you don't remember what the electronic configuration is, look in the examples of the aufbau principle, above. If you don't remember the order of filling of the orbitals, see the “orbital filling diagram, above.) Answer 14. Now write the orbital diagram for oxygen: 226
In the animation, you can see that the electrons occupy
different orbitals according to the energy level of each orbital. A
single box represents an orbital. The unpaired electron is
represented aswhereas the paired electrons in
the same orbital are represented by two arrows pointing in opposite
directions:. Watch the animation and
identify which of the following statements are correct.
Check all that apply.
The He atom has two electrons that have parallel spin in its
1s orbital.
In the...
The valence electrons of an atom are at the lowest energy level because their increased distance from the nucleus reduces their attraction to the atom's protons. true O false
Question 57 Energy that is associated with the relative positions of electrons and nuclei in atoms and molecules is called O thermal energy O chemical energy O potential energy. kinetic energy
PROBLEM: Moore's Law states that we should expect to see roughly a doubling of the maximum number of transistors on integrated circuits (a.k.a. semiconductor chips) every two years or so (see article on Moore's Law in Wikipedia (Links to an external site.)Links to an external site.). A corollary to Moore's Law is that we should also expect to see a corresponding fall in the production costs, and hence also in the prices, of semiconductors that have a given number of...
how many electrons does an atom need to completely fill the five lowest energy levels?
