Answer:
The physical properties are different ways to identify the element in the periodic table.
Step-by-step explanation:
The substance which cannot be separated by any types of external forces are called element. In periodic table, these elements are arranged based upon the atomic number with element specific symbols. In order to identify the element, two methods can be used.
If the symbol or atomic number is given, the element can be identified by correlating it with the periodic table, on the other hand, if the element is given it can be identified by the physical properties such as color, texture, flame test, etc.
