Elements are grouped by multiples of atomic number.
Elements are in order according to the number of nesutrons in their nucleus

Answer 1

The most accurate description of what is unique about how the periodic table of the elements is organized is:

Elements with similar properties are grouped together in a pattern.

In the periodic table, elements are arranged in rows (periods) and columns (groups or families) based on increasing atomic number. Elements in the same group typically exhibit similar chemical and physical properties due to their similar electron configurations. This organization allows for the prediction of the behavior of elements based on their position in the table.
