Is barium an ionic bond

Answer 1

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.

Answer 2

Barium is in Group 2A on the Periodic Table. This means that it has two valence electrons on its outer valence shell. In order to ionize, it would lose those two electrons, meaning that barium's ion charge is 2+. This makes the Barium ion Ba2+.

Answer 3

In Barium sulfate?

Barium

Ba(2+)

Answer 4

Barium Sulfate is an Ionice compound because it contains and element that is a metal. Molecular compounds are between nonmetals

Answer 5

No, barium sulfate is not soluble, so is not considered aqueous.

Answer 6

Barium forms a +2 cation.
