| Alkali Metals (Group 1) | Highly reactive metals. So reactive the they are never found uncombined in nature. Metals soft enough to be cut with a butter knife.
🗑
|
||||
| Alkaline Metals (Group 2) | Fairly reactive metals. Less reactive than alkali metals, but still never found uncombined in nature. They serve as important minerals for our body.
🗑

| Metals | Solid at room temperature except mercury, shiny luster, ductile, malleable, good conductors of heat and electricity, high density, high melting points, reactive.
🗑
|
||||
| Nonmetals | No luster, poor conductors of heat and electricity, brittle, not ductile, not malleable, low density, low melting points, less reactive than metals.
🗑

| Metalloids | Elements on both sides of the zigzag line (on the periodic table) have properties of metals and nonmetals.
