Apr 25, 2024 · An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.
2 days ago · Definition: Acid Dissociation Constant, 𝐾 𝑎. The acid dissociation constant is the equilibrium constant for the reaction of an acid with water, where the acid, H A, dissociates into H + and A – ions. The preceding 𝐾 equation includes three concentration terms, but it can be simplified to include just two.
May 2, 2024 · The periodic table contains informative cells for each element arranged by increasing atomic number and chemical properties. Each element's cell typically contains lots of important information about that element. Element symbols are abbreviations of the element's name.
