Barium 137 has 56 protons and 56 electrons.
Barium has 56 protons.
Each barium atom has 56 protons in its nucleus.
Barium 137 has 56 protons and 56 electrons.
There are four protons. Also four neutrons and four electrons
Barium (Ba) has 56 protons. Barium is an alkaline earth metal.
Barium. Atomic number 56 The reason for this is because Barium has 56 protons and the protons determin the atomic number (56).Also, that would be the same number of electrons. I hope this helped you :]
Barium's atomic number is 56, so it has 56 protons.
Barium has 81 neutrons :D
Hey there are 56 electrons and 56 protons in a barium atom (protons usually=electrons) also you should have a look on the Internet for a periodic table and print it off it has helped me allot.
There are four protons. Also four neutrons and four electrons
Proton = 1 Neutron = 1 Electron = 0.00054
Barium has 56 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a barium isotope = Mass number - 56
