None. Barium is in group 2. the electronic configuration is [Xe] 6s2.
Phosphorus has three unpaired electrons in its ground state.
Cesium has 1 unpaired electron.
An oxide ion (O^2-) has 0 unpaired electrons. It has a full outer electron shell with 8 electrons, fulfilling the octet rule.
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
There are no unpaired electrons in strontium.
