No. Mercury-201, or 201Hg, is stable.
When thallium-201 decays by electron capture, it transforms into mercury-201. In electron capture, a proton in the nucleus combines with an inner-shell electron to form a neutron and a neutrino. The resulting nuclide is one atomic number less with the same mass number.
The equation for alpha decay of mercury-201 is: ^201Hg -> ^197Au + ^4He This means that mercury-201 decays into gold-197 and helium-4 by emitting an alpha particle.
In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.
Using the formula for exponential decay, we can find that the ratio of the final quantity to the initial quantity is (1/8). Since 3 half-lives have passed (3 * 67 = 201 hours), the time elapsed is 201 hours.

Gold-201 undergoes beta- decay, with a half-life of 26 minutes to Mercury-201 ...79201Au --> 80201Hg + -10e + v-eemitting an electron and an electron antineutrino.Remember: Beta- decay involves changing a neutron into a proton, so the atomic number goes up by one, while the atomic mass number stays the same.Specifically, a down quark is changed into an up quark, resulting in the change of the neutron into a proton and in the emission of a W- boson, via the weak atomic force, that subsequently decays into an electron and an electron antineutrino.Memorize this - don't just read it - say it out loud ten times, or whatever works for you.
121 neutrons.
Mercury is a metal element. Mass number of it is 201.
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
Gold-201 is a beta/gamma emitter with a 26 minute halflife.Mercury-201 is stable and makes up 13.22% of natural Mercury.Thallium-201 is a gamma emitter decaying by K capture with a 72 hour halflife.Lead-201 is a gamma emitter decaying by K capture with a 8.4 hour halflife (or less depending on isomer).Other elements can be produced with an AMU number of 201, but there halflives are really too short to be of practical interest.
Mercury is a metal element. Atomic number of it is 80.
Mercury (Hg) has an average atomic mass of 200.59. This is an average based on the percentages of the naturally occurring isotopes of Mercury. There is an isotope of Mercury that has 201 particles in the nucleus. Since Mercury's atomic number is 80, Mercury-201 has 80 protons and 121 neutrons in its nucleus.
The atomic mass of mercury is approximately 200.59 grams per mole.
In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.
