Identify the element whose highest energy electron would have the following four quantum numbers?
ad-work [718]

C. 6, 1, 0, -1/2

Explanation:

The four quantum numbers are:

  • Principal quantum number (n): this represents the energy level in which an orbital is located.
  • Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
  • Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
  • Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.

To know the electron with the highest energy, we use the principal quantum number values.

n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............

The higher the value, the higher the energy level.

From the given quantum numbers, C has the highest energy levels.

Help!!! I need the answer for "explain how using the periodic table can help answer this question"
Tanzania [10]
Well a compound is 2 or more different molecules together. So if you see a periodic table you will see the elements to see if they are the same or not.
