What is the different about every element in the periodic table?

Answer 1

Each element in the periodic table is unique due to its atomic number, which is the number of protons in the nucleus of an atom of that element. This number determines the element's chemical properties and its placement in the periodic table. Additionally, each element has a unique combination of electrons, neutrons, and atomic mass, which further distinguishes it from other elements. The physical and chemical properties of each element are determined by its atomic structure, including the number of electrons in the outer shell and the arrangement of those electrons.
