What is streak and how is it used to identify minerals?
Streak is a powdery residue produced by minerals, it is useful because certain minerals produce specific streaks. However only minerals softer than porcelain can be identified with this technique.
What is the general trend in of metallic properties across the periodic table?
Increase in metallic properties to the left and down
