Step 1:Recall that for a neutral element,Atomic number= # of protons = # of electrons.
You are watching: How many unpaired electrons are in the vanadium atom
The atomic number of V is 23 which means V has23 electrons.
The location of V in the regular table is presented below:
Based on the figure, V belongs in thed-block in period 4so its electron configuration will contain the4s and also 3d subshells.
• s–subshell have the right to hold a best of 2 electrons
• p–subshell have the right to hold a preferably of 6 electrons
• d–subshell have the right to hold a maximum of 10 electrons
• f–subshell can hold a maximum of 14 electrons
Starting indigenous 1s, the electron construction for V is:
Step 2:In V2O3, the fee of V is +3.
The +3 fee means3 e– to be lost. Therefore, we must subtract 3 e– starting from thehighest power level (4s).
Theelectron configuration for V3+is:
