What is periodicity in properties of elements with reference to the Modern Periodic Table ? Why do all the elements of the same group have similar properties ?How does the tendency of elements to gain electrons change as we move from left to right in a period ? State the reason of this ...
{16) 1⑥ The occurence of the element with similar properties after certain regular intervals when they are aranged in increasing order to of atomic number is called periodicity. The periodic repetition of the properties is due to the recurrence of similar valence shell configuration after regular...
periodic variation of properties in elements. The key difference between Mendeleev and Modern periodic table is that the basis of the modern periodic table is mainly the electronic configuration of the elements, which we call as the atomic number whereas Mendeleev periodic table considers the atomic ...

Modern Periodic Table: The modern periodic table organizes elements into periods and groups. Elements in the same period will have electrons distributed in the same number of energy levels, while elements in the same group will have the same number of electrons....
A6 In the modern Periodic Table, elements are arranged in the order of increasing proton numbers. A student tried to re-arrange the elements in the order o Increasing relative atomic masses and got nearly the same arrangement.However, the elements, argon and potassium would have their positions...
