Answer 1

Answer:

HOPE THIS WILL HELP U☺️

Explanation:

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.

Apart from radioactivity, all are periodic properties.

(Radioactivity is a process in which nuclei of certain elements undergo spontaneous disintegration and it doesn't depend on configuration so it is not periodic)
