The term that is used to label the energy levels of electrons are principle quantum numbers and a valance band refers to the “energy levels in an atom where the electrons that participate in bonding occupy. These energy levels correspond to those of the s and p orbitals of the outermost shell of the atom being considered.” Hope this helps! :)
Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.
Answer:
The molarity of the solution is 1.7 
.
Explanation:
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units .
In this case, you know:
- moles of solute= 5.1
- volume= 3 L
Replacing:
Solving:
Molarity= 1.7
<u><em>The molarity of the solution is 1.7 </em></u><u><em>.</em></u>
