How many protons are in an ion with 36 electrons?
36 electrons is the number of electrons in the stable inert gas Krypton. (That’s why ions are more stable than atoms and atoms tend to form ions.) 35+n=80 to solve for n subtract 35 from both sides. So Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.
Which element has 36 electrons and a charge of?
What is the mass number of an ion with 36 electrons 45 neutrons and a charge?
a monotonic anion of unit charge contains 45 neutrons and 36 electrons. find the atomic number, mass number of the ion with its identification. Pritam has the correct answer, it is selenide ion.
Which ions has 36 electrons?
For example, the neutral bromine atom, with 35 protons and 35 electrons, can gain one electron to provide it with 36 electrons. This results in an anion with 35 protons, 36 electrons, and a 1− charge. It has the same number of electrons as atoms of the next noble gas, krypton, and is symbolized Br−.
What material has the shortest half-life?
Uranium-234 has the shortest half-life of them all at 245,500 years, but it occurs only indirectly from the decay of U-238. In comparison, the most radioactive element is polonium. It has a half-life of a mere 138 days.
What has a half-life of 33 years?
Experiments have shown that proton decay, if it occurs, must have a half-life in excess of 1033 years, more than 50 trillion times longer than that of bismuth and 72 billion trillion times the present age of the universe. You may wonder which naturally-occurring element has the shortest half-life.
Why are elements bigger than bismuth radioactive?
Nuclei at or just below a magic number will be more tightly bound than nuclei just above the magic numbers. Thus you’ll often find more radioactive nuclei just above a magic number: because they are less tightly bound than the magic nuclei, and thus have a larger mass difference.
What is the largest non radioactive element?
It has 83 protons and a magic number of 126 neutrons, and an atomic mass of 208.9803987 amu (atomic mass units). Primordial bismuth consists entirely of this isotope….Bismuth-209.
