take a foam ball and stick pipe cleaners in it.stick 137 small wades of paper and stick the pipe cleaners in the paper wads. 61 one should be painted on color and the other 56 another color. join up some pipe cleaners and stick it in the nucleus.then take 56 more wad oif paper a differnt color and stick them on to get the number of shells needed. REMEMBER that the k shell can hold up to 2 and the L can hold 8 and the m shell holds 18 and the n shell holds 32

What is the mass of a barium atom?
The mass of a barium atom is approximately 137 atomic mass units (u).
How many electrons does Baruim have?
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.
What type of bond occurs between barium and sulfur?
An ionic bond would occur between sulfur and barium.
Is barium an ionic bond?
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
