Question

Why do the rows in the periodic table get progressively longer as you move down the table? For example, the first row contains two elements, the second and third rows each contain eight elements, and the fourth and fifth rows each contain eighteen elements. Explain

The rows in the periodic table grow progressively longer because you are sorting elements according to their frequency of occurrence in nature.

The rows in the periodic table grow progressively longer because you are adding rare and synthetic elements.

The rows in the periodic table grow progressively longer because you are adding non-stable elements.

The rows in the periodic table grow progressively longer because you are adding sublevels as the n level increases.

Answer 1

option D

As we add the electrons into more and more sublevels ( like p, d and f) the number of elements increase and we have more elements in each period progressively.
