Radon (Rn) is a noble gas with an atomic number of 86. Its electron configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁶, which means all of its electrons are paired. Therefore, radon has zero unpaired electrons.
Radium (Ra) has an atomic number of 88, which means it has 88 electrons. Its electron configuration is [Rn] 7s², indicating that the 7s subshell is fully filled with two electrons, leaving no unpaired electrons. Therefore, radium has zero unpaired electrons in its ground state.
There are no unpaired electrons in strontium.
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.
In group 3A elements, or elements in group 13, have only one unpaired electrons.
