• They are highly volatile

Why are alloys of transition metals common?

• They are all liquids
• They have very different colors
• Similar radii and other characteristics of transition metals
• They are all highly reactive

What condition regarding atomic size favors the formation of homogeneous solid solution alloys?

• Metallic radii within about 15 percent of each other
• One metal must be significantly larger
• One metal must be significantly smaller
• Atomic masses must be very close
