![]() ![]() ![]() The below infographic presents the differences between barium and strontium in tabular form for side-by-side comparison.īarium is a chemical element having the symbol Ba and atomic number 56, while Strontium is a chemical element having the symbol Sr and atomic number 38. Moreover, barium is comparatively softer than strontium. The key difference between barium and strontium is that barium metal is more chemically reactive than strontium metal. What is the Difference Between Barium and Strontium?īarium and strontium are important alkaline earth metals in group 2 of the periodic table. It is an s block element with the electron configuration 5s2. The melting point of strontium is high (1050 K), and the boiling point is also high (1650 K). It is a solid at standard temperature and pressure. It is an alkaline earth metal in group 2 and period 5 of the periodic table. Strontium is a chemical element having the symbol Sr and atomic number 38. Therefore, metallic barium is stored under oil or in an inert atmosphere. Barium can react with chalcogens in the form of exothermic reactions, releasing energy. Recently, research studies have found a +1 barium form as well. The normal oxidation state of barium is +2. However, barium is more reactive than these metals. When considering its chemical reactivity, barium has a reactivity similar to magnesium, calcium, and strontium. This is because this metal is difficult to purify, which makes it difficult to figure out most of its properties. More importantly, barium has a moderate specific weight and a high electrical conductivity. Moreover, barium is a paramagnetic substance. The natural occurrence of barium can be described as primordial, and it has a body-centered cubic crystal structure. The density is very high as well (about 3.5 g/cm 3). ![]() It has a high melting point (1000 K) and a high boiling point (2118 K). It is an s-block element with the electron configuration 6s2. This chemical element is found in the periodic table in group 2 and period 6 under alkaline earth metals. Upon oxidation in air, the silvery-white appearance suddenly fades to give a dark grey layer consisting of the oxide. It appears as a silvery-gray metal with a pale yellow tint. Summary – Barium vs Strontium What is Barium?īarium is a chemical element having the symbol Ba and atomic number 56. Although they are in the same group, they belong to different periods, which makes them slightly different from each other in their properties. This is because these metal atoms have an ns 2 electron configuration. The key difference between barium and strontium is that barium metal is more chemically reactive than strontium metal.īarium and strontium are two members of the alkaline earth metals group (group 2) of the periodic table. ![]()
