Barium (Ba) has an atomic number of 56, meaning it has 56 electrons. The electron configuration for barium is [Xe] 6s², indicating that it does not have any electrons in the 5p subshell. Therefore, barium contains 0 electrons in the 5p subshell.
Barium 137 has 56 protons and 56 electrons.
Examples: Ca, Mg, Ba, Sr, Ra, etc.
Ba2+ is the ion of the Ba atom. That means it has given away two electrons to other atoms in order to reach a stable state with 8 electrons in its outer shell.
Among the elements Scandium (Sc), Chlorine (Cl), Barium (Ba), and Selenium (Se), only Scandium (Sc) and Chlorine (Cl) are paramagnetic. Scandium has unpaired electrons in its electron configuration, making it paramagnetic. Chlorine, in its gaseous form, also has unpaired electrons, contributing to its paramagnetic nature. Barium (Ba) and Selenium (Se) are not paramagnetic; Ba is a noble gas with all paired electrons, while Se has a stable electron configuration with no unpaired electrons.
All should lose 2 electrons to attain the nearest noble gas configuration
Barium (Ba) has 2 valence electrons in its outer shell. Therefore, it does not have any 5p electrons.

Barium 137 has 56 protons and 56 electrons.
Barium (Ba) has an atomic number of 56, which means it has 56 electrons in a neutral atom. The "2" you mentioned likely refers to the charge on the barium ion (Ba2+), which means it has lost two electrons, resulting in 54 electrons in the Ba2+ ion.
Barium has two valence electrons, as can be deduced from its placement in Group 2 of the modern periodic table.
Ba2+ ion has a total of 56 electrons. Barium (Ba) has 56 electrons in its neutral state, and when it loses two electrons to become Ba2+, it now has 54 electrons remaining.
Examples: Ca, Mg, Ba, Sr, Ra, etc.
Krypton (Kr) has a total number of 36 electrons, which is the same as the number of core electrons in barium (Ba).
Ba2+ is the ion of the Ba atom. That means it has given away two electrons to other atoms in order to reach a stable state with 8 electrons in its outer shell.
Among the elements Scandium (Sc), Chlorine (Cl), Barium (Ba), and Selenium (Se), only Scandium (Sc) and Chlorine (Cl) are paramagnetic.
