Question

what do you understand by the term periodicity does the period city in properties is a function of Valence Electrons​

Answer 1

Answer:

Explanation:

This phenomenon is known as the periodicity of elements. The periodic properties of elements occur due to the recurrence of similar electronic configuration that is having the same number of electrons in the outermost orbit. In a particular group, the number of valence electrons remains the same.

Answer 2

Answer:when the elements are arranged in order of increasing atomic number elements with similar chemical property e are repeated at infinite intervals this is known as periodicity jet this is due to the periodicity in the number of electrons in the outermost shell of the atoms of inter electron in electrons having the same number of valence electrons are group together elements for each group are similar in chemical properties
