COMPARE AND CONTRAS




 A. Compare
Compare: is a level that emphasizes equation or "positive" level




       timbal (Pb)
timah (Sn)

Example:
1. tin is class IV A
2. lead is class IV A
3. lead is metal
4. lead is metal


B. Contras
Contrast: Is a level that emphasizes differences. In this explanation you will be taken to understand 2 types of Rankings, namely: Comparison and Superlatives
      

                                      Natrium (Na)                               Magnesium (Mg)

1. Comparative: at the following comparison level, you must have at least 2 Subjects.
Example:
1. Na is more reactive than Mg


2. Superlatives: at the following comparison level, you must have at least 3 or more Subjects.
Example:
1. Calcium is more reactive than magnesium, but sodium is more reactive than both
 

C. Thinking map

 
Thinking Maps are a set of graphic organizer techniques used in primary and secondary education ("K-12"). There are eight diagram types that are intended to correspond with eight different fundamental thinking processes. They are supposed to provide a common visual language to information structure, often employed when students take notes.
Thinking Maps are visual tools for learning, and include eight visual patterns each linked to a specific cognitive process. Teachers may apply Thinking Maps in all content areas and all grade levels. The eight map types are:
used for defining in context
used for describing with adjectives
used for sequencing and ordering events
used for identifying part/whole relationships
used for classifying or grouping
used for comparing and contrasting
used for analyzing causes and effects
used for illustrating analogies

    1. Symbol: Mg
      Nomoratom: 12
      Beratatom: 24,305
      Classification: Metalalkalitanah
      Fase at TemperatureRoom: SolidCapacity: 1,738grampcmcornedThe melting point: 650 ° C, 1202 ° FThe boiling point: 1091 ° C, 1994 ° FFound by: Joseph Blackdi in 1755. Isolated by SapphumphryDavypada in 1808. In standard magnesium conditions Is a lightweight metal with a silvery-white color. Because of the air, the magnesium will fade and become protected by a thin layer of oxide.

  2. Why Na is more reactive than mg?

    1. Because Na is in Group IA, while Mg is in the class IIA, so the group IA more reactive than the group IIA

  3. why Sn is used to wrapping cigarettes?

    1. Because Tin has stainless resistance when exposed to water but can not stand exposed to acid and alkali. It is not too affected by water and oxygen at room temperature, not rusty and not easily corrosive. Tin is commonly used as a protective coating for other metals. This layer is useful to prevent further oxidation by oxygen present in the air or water. However, at high temperatures the tin can react with oxygen to form lead oxide.

    1. To make it easier to know the differences and similarities of what we want to compare.
