About this deal
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity.

During the development of modern atomic physics and quantum mechanics theory, a precise and detailed understanding of the electronic structure of noble gases and other atoms was obtained, fully explaining the periodic law.The periodic table arrangement allows us to look for patterns in elements' chemical and physical properties and predict how other elements in the same area might behave.

There are currently no commercial uses for it, but it’s used as a target to synthesise heavier elements due to its longer half-life and availability.
Even though each atom has roughly the same number of atomic mass units, the atomic mass on the periodic table is a decimal; this is because the number is a weighted average of the various naturally-occurring isotopes of an element based on their abundance. Volatile strontium salts, which impart a crimson colour to flame, are used in pyrotechnics and flares.

Although relatively inert, it is affected by halogens and dilute alkali and unaffected by most acids.They are the only group whose elements at room temperature include solid, liquid, and gaseous forms of matter. This element behaves like lutetium, is trivalent, and could be classified as the first 7th-period transition metal.
