Answer» s in modern periodic table follow periodicity, I. e., the similar properties of ELEMENTS are REPEATED after a FIXED interval, after fixed no. of elements, elements have similar properties. all the elements of same GROUP have similar properties because elements of Same group have same no. of valence ELECTRONS. the properties of elements depend upon their valence electrons. tendency of elements to gain electronsincrease on moving from left to right in a period this is because the number of Valence Electrons increase from left to right in a period the elements with less number of Valence Electrons have more tendency to lose electrons than to gain them to attain stability |
