After the Pauling electronegativity (1,13) promethium is a reactive metal but the chemistry of Pm is only superficially known.
The valence of ions in solution is +3. Promethium compounds known: halides, oxides, nitrates, sulfates, hydroxides etc.
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
The physical properties of minerals are determined by their chemical composition and atomic structure.
The physical properties of compounds do not include chemical reactivity, which relates to how a substance undergoes chemical changes. Physical properties pertain only to characteristics such as color, melting point, boiling point, density, and solubility.
Sulfur is a chemical element, not a property. Its chemical symbol is S and it is typically found in its solid form. It exhibits various chemical properties and can form different compounds with other elements.
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
Promethium has similar chemical properties as cerium and other lanthanoids.
Promethium has similar chemical properties as cerium; the oxidation state is 3+.
Promethium is the only lanthanide that is radioactive and does not have stable isotopes. It is also challenging to study due to its radioactivity. Additionally, promethium has unique chemical properties compared to other lanthanides.
The chemical symbol of promethium is Pr.
No. Chemical and physical properties are different.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Promethium is a chemical element, a metal.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Promethium is a chemical element, atomic number 61.
The chemical symbol of promethium is Pm.
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
