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.

Gain or lose.
The exchange of electrons in chemical bonding seeks to fulfill the octet rule. There are some exceptions, such as with hydrogen and helium, whose valence shells have a capacity of two electrons.
