Not known but very probable not flammable.
Hafnium-174 is the most common isotope of hafnium, making up about 31% of naturally occurring hafnium.
Hafnium can react with a variety of elements to form compounds, such as oxygen to form hafnium dioxide (HfO2) or with chlorine to form hafnium tetrachloride (HfCl4). It is generally considered to be unreactive at room temperature but can react with strong acids and alkalis under high temperature conditions.
Hafnium is a dense, ductile metal that is relatively soft compared to other metals, such as steel or titanium. It can be easily machined and formed, but it does have a high melting point and is known for its high resistance to corrosion.
The atomic number of hafnium is 72. So there is 72 protons.
Hafnium typically forms a +4 oxidation state in its compounds, resulting in the formation of Hf^4+ ions. These ions have a charge of +4 and are commonly found in hafnium compounds.
The element hafnium has no distinctive odor, nor is it magnetic at room temperature. There are five stable isotopes of this element, so most hafnium is not radioactive. But there are a number of isotopes that have been synthesized that are radioisotopes. Additionally, this transition metal is not explosive or even flammable. A link can be found below.
Hafnium is malleable.
Hafnium is a shiny, silvery metal that does not have a distinct color.
Pure hafnium doesn't exist in the nature; hafnium form many compounds.
Fine powders of hafnium are pyrophoric.
There are 37 isotopes of Hafnium.
Hafnium-174 is the most common isotope of hafnium, making up about 31% of naturally occurring hafnium.
Hafnium is found in tandem with zirconium deposits. It is separated from the zirconium during refinement as hafnium chloride. It is then reduced with magnesium to produce pure hafnium.
Hafnium is a metal, steel grey appearance.
Hafnium is a single element and therefore nonpolar.
Yes, hafnium is reactive, but not like sodium or potassium.
The density of hafnium is 13,31 g/cm3.
