How many neutrons are in 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
What is the mass number of an ion with 109 electrons 159 neutrons and a plus 1 charge?
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.
How many protons electrons and neutrons does lawrencium have?
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.
How many neutrons are in larencium?
Larenicium has 103 protons, indicated by its atomic number, and typically around 159 neutrons, based on its most common isotope, Lawrencium-262.
How many protons and neutrons does Mendelevium have?
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.
