The barium atom has a much bigger radius.
An atom of osmium has 76 protons in its nucleus.
an osmium atom has 76 protons.
An osmium atom has 76 of each.
An osmium atom has 76 protons.
A barium atom has two valence electrons.
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.
The barium atom (neutral) contain 56 electrons.
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'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.
76
The atomic weight (not mass) of barium is 137,327(7).
76 of each.
