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
The mass number is the sum of the number of protons and neutrons in an atom. Since the ion has 109 electrons and a +1 charge, it means it has 110 protons. With 159 neutrons, the mass number would be 110 (protons) + 159 (neutrons) = 269.
Lawrencium has 103 protons and electrons. The number of neutrons in lawrencium can vary due to different isotopes, but a common isotope, lawrencium-262, has 159 neutrons.
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.
The mass number of an ion is the sum of its protons and neutrons. Since the ion has 107 electrons and a plus 1 charge, it means it has 106 protons to balance the charge. Adding the protons and neutrons (106 + 159), the mass number of the ion is 265.

Rutherfordium is a synthetic element with atomic number 104. It has 104 protons and a variable number of neutrons, depending on the isotope.
Rutherfordium has 104 protons; the isotope with the longest half-life (263Rf) has 159 neutrons.
That's two integers, not one.
The mass number is the sum of the number of protons and neutrons in an atom. Since the ion has 109 electrons and a +1 charge, it means it has 110 protons. With 159 neutrons, the mass number would be 110 (protons) + 159 (neutrons) = 269.

A Rutherfordium atom has 104 protons, 157 neutrons, and 104 electrons.
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.
The most massive particles in an atom are the protons and neutrons, which are located in the atomic nucleus. Protons and neutrons are about 2000 times more massive than electrons, which orbit around the nucleus.
