Question | Answer |
---|---|
Non-Metals | No luster, low density, low melting point, not ductile. |
Metalloids | Mixture of metals and non-metals. |
Metals | Conductors, ductile, malleable, high melting point. |
Periods | Periods are going vertical and are numbered 1-7 on the PT, their atomic number increases from left to right. |
Groups | Groups are goin horizontal and are numbered 1-18, the left side is more reactive then the right. |
Reactive Atoms | Very unstable atoms, the mot reactive are on the left side of the PT. |
Stable Atoms | Rarely bond with other atoms, stable atoms are on the right side of the PT. |
Alkali Metals | Highly reactive metals, they are never found uncombined in nature, also are very soft. |
Alkaline Matels | Fairly reactive but still are never found uncombined in nature, also serve as important minerals to our body. |
Transition Metals | Less reactive, they are hard, dense metals that are useful as building materials, jewelry and coins. |
Noble Gases | Unreactive gases, do not react naturally, always found on their own in nature. |
