No, Nobelium, to the honor of Alfred Nobel, not naturally occurring, instable isotope of the 'trans-uranic' actinides
the known table of elements stops at 118 protons in an atom max. so the question is probably which atom has >102< protons which is radioactive Nobelium at its most stable isotope. 102/256 No
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
Molecules. However it is surprising when you consider a truly heavy element how many lighter ones are needed to "win" the argument. Consider nobelium-259 it has 259 protons and neutrons and 102 electrons. Whereas heptane C7H16 has 100 protons and neutrons and 58 electrons so quite a way short! It takes an alkane of around C21H44 to get close.
Ruthenium typically has 102 neutrons in its nucleus.
Nobelium, with the chemical symbol No, is the chemical element with the atomic number 102.
The element with an atomic number of 46 is palladium; its mass number, 102, indicates that this atom is contains a disproportionate number of neutrons to protons (56/46), making it a lighter isotope (Pd102) that represents only 1.02% of all natural palladium.
157; you figure that out by taking the atomic mass (259) and subtract it by the # of protons (102) and the answer is the # of neutrons. ( the atomic #, # of protons, and # of electrons are always the same # 102 ). But each isotope of nobelium has a different number of neutrons, depending on the atomic mass.

99.9% of an atom's mass is concentrated in the nucleus, with protons and neutrons having almost the same mass, with neutrons being slightly higher. So your question would be, 'What atom has the most protons and neutrons combined?' And that answer is Nobelium. Nobelium has 102 protons and 160 neutrons which makes it the most 'massive' atomic particle, even more so then Lawrencium which has 103 protons but only 159 neutrons. Of course, in a few months, we could have a new, more massive element.
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.

Rhenium has 75 protons, 75 electrons and 111 neutrons.The number of protons is equal to the number of electrons.Neutrons can be calculated by subtracting the number of protons from the atomic weight.In this case atomic number is 186 ==> the nr of neutrons = 186-75=111.
Nobelium has 102 protons.
Ruthenium typically has 102 neutrons in its nucleus.
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an No isotope - 102
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an No isotope - 102
