Solution

1)the main aim of classifying elements is to-
create order out of chaos
to learn faster about elements.
2)the basic property used in making periodic table is atomic number and chemical properties
3)modern periodic law-
the properties of elemnts are periodic functions of their atomic number
4)metals - towards the left side
non metals -right side
metalloids - between both
