The barium atom (neutral) contain 56 electrons.
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.
Krypton (Kr) has a total number of 36 electrons, which is the same as the number of core electrons in barium (Ba).
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
13 in the neutral atom, 10 in the Al3+ ion
There is none, but a neutral atom is called a neutron. There is no neutral element.
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
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.
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.
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.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
Barium has an atomic number of 56, meaning it has 56 electrons in its neutral state. These electrons are arranged in energy levels and orbitals around the nucleus following the rules of quantum mechanics. The electron configuration of barium is [Xe] 6s2, indicating that it has two electrons in the outermost 6s orbital.
That depends on the element you are considering. For a neutral atom, the number of electrons = number of protons = atomic number
protons and electrons
it is protons and electrons. your welcome and vote this best answer!
protons
Krypton (Kr) has a total number of 36 electrons, which is the same as the number of core electrons in barium (Ba).
Barium's atomic number is 56. Thus, barium has 56 protons and 56 electrons. Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2. So, barium has 2 electrons in its highest energy level, level 6.
