How many unpaired electron are in Cr2+?
In the case of $C{r^{2 + }}$ ion, the number of unpaired electrons is 4.
What is the electron configuration for Cr2 +?
After the 4s is full we put the remaining four electrons in the 3d orbital and end with 3d4. Therefore the expected electron configuration for Chromium will be 1s22s22p63s23p44s23d9.
How much unpaired electrons does oxygen have?
two unpaired electrons
In ground state the oxygen molecule has two unpaired electrons, each of which are located in a different pi* antibonding orbital (Figure 3). These two electrons rotate about their own axis in parallel spins.
Does oxygen have 2 unpaired electrons?
Therefore, the ground state of atomic oxygen has two unpaired electrons (bi-radical), and is designated as 3P (“triplet P”) state.
Which element has the highest number of unpaired electrons?
Only one unpaired electron is present. Hence, the species that has a maximum no. of unpaired electrons is Fe2+.
How do you find unpaired electrons in O2?
O2Has two bonds, one is sigma bond and other is pi-bonded. The energy diagram of O2molecule is: The electrons in π∗2Px and π∗2Py remain unpaired. So, there are two unpaired electrons in O2.

What is meant by unpaired electron?
In chemistry, an unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair. Each atomic orbital of an atom (specified by the three quantum numbers n, l and m) has a capacity to contain two electrons (electron pair) with opposite spins.
Why does oxygen have unpaired electrons?
With 12 valence electrons (6 from each O atom), there are only 2 electrons to place in the (π⋆npx,π⋆npy) pair of orbitals. Hund’s first rule dictates that one electron occupies each orbital, and their spins are parallel, giving the O2 molecule two unpaired electrons.
