Is Argon classified as a metal or as a non-metal? Where is most of the mass in an atom? What are sulfates commonly found in? Where would the electrons in the 3d sublevel be found? Where are electrons located in an atom? What do potassium, holmium, and protactinium have in common?
It is a relatively soft, silvery, fairly corrosion-resistant and malleable metal. Like a lot of other lanthanides, holmium is too reactive to be found in native form, as pure holmium slowly forms a yellowish oxide coating when exposed to air. When isolated, holmium is relatively stable in ...
