Guida verificata passo dopo passo1
Understand that the periodic table is a systematic arrangement of elements based on their properties.
Recall that each element is defined by its atomic number, which is the number of protons in its nucleus.
Recognize that the periodic table is primarily arranged in order of increasing atomic number, not by atomic mass or other criteria.
Note that arranging by atomic number ensures elements with similar chemical properties fall into the same groups or columns.
Conclude that the correct way elements are arranged in the periodic table is by increasing atomic number.
