56.
Proton = 1 Neutron = 1 Electron = 0.00054
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.
there are no atoms in a proton. a Proton is a part in the nuleus of an atom. the other parts of an atom are neutrons and electrons
Barium's atomic number is 56. Thus, an atom of barium has 56 protons in it. To keep it electrically neutral then, a barium atom must also have 56 electrons per atom.
Any neutral atom of barium contains 56 electrons, the counter charge for the 56 protons contained in the nucleus of a barium atom, as indicated by its atomic number, 56.
A barium atom has two valence electrons.
There are four protons. Also four neutrons and four electrons
A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.
The atomic number of barium is 56. So there are 56 protons and 56 electrons.
Hydrogen (atom number 1) has one proton, that's why it is number 1!
Each barium atom has 56 protons in its nucleus.
The symbol is Ba. The number of neutrons equal the number of protons.
