Elements are arranged in order of increasing atomic number, which corresponds to the number of protons in their nuclei. This arrangement is the basis for the Periodic Table, where each element's position reflects its atomic number. Neutrons, while important for the stability of the nucleus, do not determine the order of elements in the periodic table. Therefore, the atomic number is the key organizing principle.
The sum of protons and neutrons is the atomic mass.
No, protons, neutrons, and electrons are not elements. Protons and neutrons are subatomic particles found in the nucleus of atoms, while electrons orbit the nucleus. Elements are substances made up of one type of atom, characterized by the number of protons in their nucleus.
neutrons and protons
The mass number of an element is equal to the sum of the elements neutrons and protons.
The individual protons and neutrons are basically indistinguishable; they don't have different names.
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
The periodic table used to be arranged by increasing atomic mass. Now, it is arranged by increasing atomic number (number of protons in an atom of element).
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons
Protons, neutrons and electrons
An atom is made from neutrons, protons and electrons; neutrons and protons contain quarks and gluons.
The sum of protons and neutrons is the atomic mass.

LOL! Nah they aren't.
