how to learn whole periodic table in 2 days for exam???

Answer 1

Identify the different parts of each element.

Generally, to learn the periodic table, you will need to know the element's name, symbol, atomic number, and occasionally the atomic weight. These are all contained within the element's square on the table. [1]
The element name is the word associated with the element. It usually appears in small letters under the symbol. Silver, for example, is the name of an element.
The symbol is formed by one or two letters that represent the element. These are the big letters in the box. Ag is the symbol for silver.
The atomic number is the number above the symbol. It tells you how many protons the element has. The periodic table is arranged numerically according to atomic number. The atomic number of silver is 47.
The atomic weight or mass shows the average size of an atom. This is the number below the symbol. Silver's atomic weight, for example, is 107.868.
