In group 3A elements, or elements in group 13, have only one unpaired electrons.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
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.
Nickel has two unpaired electrons.

Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
Silicon has 0 unpaired electrons. It is in group 14 of the periodic table and has 4 valence electrons, which will form covalent bonds, leaving no unpaired electrons.
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.
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
