seaborgium!
Seaborgium (106Sg) is a synthetic element whose most stable isotope 271Sg has a half-life of 1.9 minutes. Number of neutrons in Sg-271 is 271-106= 165 neutronsA new isotope 269Sg has a potentially slightly longer half-life (ca. 2.1 min) based on the observation of a single decay. This one (Sg-269) has 269-106= 163 neutrons
An atom contains equal no of electron and proton. since this ion contains +1 charge it means it has 109 protons i.e one more than electron . As of mass no it's always sum of no of neutrons +no of protons So the answer is 266
Lawrencium has 103 electrons and protons. The number of neutrons is different for each of the 12 isotopes of Lr.
Larenicium has 103 protons, indicated by its atomic number, and typically around 159 neutrons, based on its most common isotope, Lawrencium-262.
Mendelevium is element 101, so it has 101 protons. Several isotopes are known, with atomic masses ranging from 245 to 262, hence from 144 to 161 neutrons. The most stable, with half-lives measured in weeks rather than hours or less, have atomic mass 258 and 260, thus 157 and 159 neutrons.
If the ion has a +1 charge and has 107 electrons, that means that it originally had 108 electrons, and therefore has 108 protons. The mass number is the sum of the protons and neutrons, 108 + 159, and therefore is equal to 267.

Rutherfordium has 104 protons; the isotope with the longest half-life (263Rf) has 159 neutrons.

That's two integers, not one.

It contains 104 electrons/protons and 159 neutrons.

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.
