Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
You can determine the number of unpaired electrons in an element by examining its electron configuration. Unpaired electrons are found in the outermost energy level, and you can count them by looking for half-filled or singly occupied orbitals in the notation of the element.
Iron (Fe) is the element that has 4 unpaired electrons in its electron configuration.
In group 3A elements, or elements in group 13, have only one unpaired electrons.
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
Phosphorus, which is the 15th element, has the most unpaired electrons among the first 20 elements. It has three unpaired electrons in its outer shell.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
There are no unpaired electrons in strontium.
Stadium (St) is an element with the atomic number 51. It has a ground-state electron configuration of [Kr] 4d¹⁰ 5s² 5p³. In this configuration, the 5p subshell has three electrons, which are unpaired. Therefore, there are three unpaired electrons in stadium.
