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.
Some physical properties of promethium are it is a metal, solid and has an atomic weight of 145. One of its chemical properties is that it is unstable.
It is estimated that the Vickers hardness of promethium is 617,8 MPa.
H2O is not a property, it is a substance with physical and chemical properties.
*isomorphic have different chemical and physical properties and poly morphous have same chemical and physical properties
Neither. Sulfur is an element by it self , that has its own physical and chemical properties.
These are examples of physical properties. They are NOT chemical properties!
copper and oxygen
Promethium has similar chemical properties as cerium and other lanthanoids.
Promethium has similar chemical properties as cerium; the oxidation state is 3+.
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.
The chemical symbol of promethium is Pr.
Shiny and silvery are not chemical properties. These are physical properties.
Physical and chemical properties of LPG
what are the physical properties of batteries
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...)
it changes chemical properties
Chemical Properties If it reacts (reactivity) If it corrodes (corrosion) Physical Properties malleable ductile conductivity magnetic
Color and density are physical properties. Odor and solubility are chemical properties.
