The electron configuration is [Kr] 4d5 5s1http://www.webelements.com/molybdenum/atoms.html
To determine the number of valence electrons for an ion, we need to consider the electron configuration of the neutral atom and take into account whether electrons have been gained or lost.
The neutral atom of the element in question is molybdenum (Mo), which has an atomic number of 42. The electron configuration for molybdenum is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d⁶.
When an atom forms an ion, it either gains or loses electrons to achieve a stable electron configuration. In the case of Mo+3, it means that three electrons have been lost.
To find the electron configuration for Mo+3, we start by removing three electrons from the highest-value quantum energy level, which is 5s. Therefore, the electron configuration for Mo+3 would be 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d⁶.
Based on this electron configuration, we can determine that Mo+3 has a total of 18 valence electrons.
