What does hafnium react with?
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.
Is hafnium and element or compound?
Hafnium is an element, not a compound. It is a transition metal with the atomic number 72 and symbol Hf.
How many valence electrons are in the outer shell of Hafnium with an atomic number of 72?
Hafnium has 2 electrons in its first shell and 8 electrons in its second shell. Therefore, in the outer shell of hafnium, there are 2 + 8 = 10 valence electrons.
What is the most common isotope in hafnium?
Hafnium-174 is the most common isotope of hafnium, making up about 31% of naturally occurring hafnium.
What type of ions will nonmetals form?
Metals form cations and non-metals form anions.
Is hafnium combined or uncombined?
Pure hafnium doesn't exist in the nature; hafnium form many compounds.
What does hafnium form?
The cation Hf4+.

Is hafnium malleable?
Hafnium is malleable.
What is the color of hafnium?
Hafnium is a shiny, silvery metal that does not have a distinct color.
How many valence electrons are in the outer shell of Hafnium with an atomic number of 72?
Hafnium has 2 electrons in its first shell and 8 electrons in its second shell. Therefore, in the outer shell of hafnium, there are 2 + 8 = 10 valence electrons.
Can you burn hafnium?
Fine powders of hafnium are pyrophoric.
How many isotopes does hafnium have?
