Because an atom of element has the same number of electrons as of protons and the number of protons in an atom is the same as the atomic number of the atom, the answer to this is whichever element has the highest atomic number yet synthesized.
The element with the highest atomic mass is Oganesson.
The element with the largest atomic number on the periodic table is Oganesson, with the atomic number 118.
To calculate the number of neutrons in an element, you subtract the atomic number (number of protons) from the atomic mass (nearest whole number). The atomic mass is the weighted average of the isotopes of that element found in nature. For example, for carbon, the atomic number is 6 and the atomic mass is around 12, so the number of neutrons would be 12 - 6 = 6.
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number. When dealing with an element with no net charge, the atomic number = the number of protons and also the number of electrons. The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
