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.

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.
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.
102 ( the atomic #, # of protons, and #of electrons are always the same )
For this you need the atomic (molecular) mass of Al2O3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Al2O3= 102 grams408 grams Al / (102 grams) = 4.00 moles Al
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.
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.

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
Mass of C-12 atom =12 amu8.5 times of mass of C-12 atom = 12 x 8.5 = 102 amuSo molecular mass of XY = 102 amusource- www.examville.com
The symbol of an atom with 102 protons and 152 neutrons is 254 Es, which stands for Einsteinium. This element is a synthetic radioactive metal and belongs to the actinide series on the periodic table.

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

There are many equations that equal 102 in subtraction (eg.104-2 and 204-102) All there is to it is to take a number that is greater than the number 102 and subtract 102 from it. Then you take that answer and place it as the number you subtract.For example,a number greater than 102 is 104.104-102 is 2. So the equation is 104-2=102.
