Question

"The properties of the elements are a periodic function of their atomic number " Justify the statement with suitable example

Answer 1

in the modern periodic table all the elements are arranged in the function of the periodic function like before it was only on the atomic mass not on the atomic number and the elements are arranged there are different place for Eiffel tower it was not on the men's the table and all the elements are on the basis of their atomic number plate is easy to count

Answer 2

ANSWER

There are various physical properties of elements such as melting points, boiling points, heat of fusion, vaporisation, etc., which show periodic variations. The cause of periodicity in properties is the repetition of similar outer electronic configuration after certain regular intervals. e.g. All the elements of group 1 have similar outer electronic configuration. K L M N Li =2 1 Na =2 8 1 K = 2 8 8 1 %3D Therefore, due to similar outermost electronic configuration, all the elements of group 1 have similar properties, e.g. sodium and potassium 4/6 both are soft and reactive metals. They all form basic oxides and their basic character increases down the group. Hence, from above examples we can say that the properties of the elements are a periodic function of their atomic number.
