Question

what is unique about how the periodic table of the elements is organized? (1 point) elements are grouped by multiples of atomic number. elements are in order according to the number of neutrons in their nucleus. elements with similar properties are grouped together in a pattern. elements are in order so that each element has an atomic mass that is 1 greater than the previous element.

Explanation:

The periodic table organizes elements by atomic number. Elements with similar properties are grouped together in columns (groups) and rows (periods). Atomic mass increases generally as atomic number increases, but it's not the organizing principle. Neutron - number is not the basis for the overall organization. Grouping by multiples of atomic number is incorrect.

Answer:

Elements with similar properties are grouped together in a pattern.
