Barium is an Alkaline Earth Metal found in Group 2 of the Periodic Table.
BaSo3
Ba(NO3)2
This is possible because the baruim sulfate formed is insoluble.
No. Barium is an alkaline earth metal (or group 2 element). Noble gases are group 18 elements.
Barium is found in period 6 of the periodic table.
Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
Barium sulfate is an inorganic compound. It is a white crystalline solid that is insoluble in water and is commonly used as a contrast agent in medical imaging procedures such as X-rays.
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.
Barium is a chemical element with symbol Ba. It is a soft, silvery alkaline earth metal so its streak would be grey. Ba does not occur in elemental form in nature so a petrologist/mineralogist/geologist would never test its streak.
Potassium Chromate precipitates with and coumpnd that contains a cation and NO3, also known as the polyatomic ion Nitrate. Three common examples of this are Zinc Nitrate (Zn(NO3)2) Silver Nitrate (AgNO3) and Baruim Nitrate (Ba(NO3)2)
The number of neutrons in one atom of barium is typically 81. Barium has an atomic number of 56, which represents the number of protons in the nucleus. The number of neutrons is calculated by subtracting the atomic number from the atomic mass (usually rounded to the nearest whole number).
A solution in which the solvent is not water would still be called a solution. If you really needed to emphasise the fact that it wasn't water, you might refer to it as a 'non-aqueous solution'
