    • What is the simplest element on a periodic table?

      The Periodic Table of Elements What are Atoms? Atoms are the simplest and smallest particle composed of protons, electrons, and neutrons. The number of protons in the nucleus of an atom is equal to its atomic number. Normally, the number of protons equals the number of electrons. The Atom's Family Protons, Neutrons and Electrons A proton is a ...

    • What is the highest atomic number on the periodic table?

      Atomic number is easy because it is an integer that increases as you move from left to right across the table. The lowest atomic number is 1 (hydrogen), while the highest atomic number is 118. Examples: The atomic number of the first element, hydrogen, is 1.

      24.31 amu represents the mass of a hypothetical average magnesium atom. Mathematics tells that an average of data points is a more reliable representation of the data than any individual value; we remain consistent with that principle here. The mass reported on the periodic table for magnesium is 24.31 amu. See the periodic table.

      From the periodic table we find that phosphorus’ atomic number is 15 so there are 15 protons. Since the mass number is 32, the number of neutrons is Z = A – N = 32 – 15 = 17. 2.41 The isotope symbol takes the form where the mass number is the neutrons plus protons and the charge is determined by the protons and electrons.
