1 Σεπ 2024 · Protons, neutrons and electrons of all elements are mentioned in the table below (You will get the List + Shell diagram of all the elements.)
1 Σεπ 2024 · The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element. To find the number of neutrons, subtract the element’s atomic number from its atomic mass (the number listed underneath the element).
Scientists distinguish between different elements by counting the number of protons in the nucleus (Table \(\PageIndex{1}\)). If an atom has only one proton, we know that it's a hydrogen atom. An atom with two protons is always a helium atom.
From the periodic table, we find that it has 29 protons. The mass number (65) is the sum of the number of protons and neutrons. Therefore, we can subtract the number of protons from the atomic number to get the number of neutrons: # n = A – Z = 65 – 29 = 36.
Number of Protons = Atomic Number. Number of Electrons = Atomic Number. Number of Neutrons = Atomic Mass – Atomic Number. In the below table we list the number of protons, neutrons and electrons for each element in the periodic table.
