This article is about Aktinum. Of the 19 quinium isotopes, the most widely known is CM and CM.It emits α-particles, but has a much shorter half-life than americium isotope.Elements are rarely released of γ-lines, but they emit neutrons when they are spontaneous fission.It is CM that the half-life is long among the isotopes of quinium, and all α-particles are released.Neutral irradiated with plutonium or amy hydraulic is produced as a mixture.When a short irradiation, the mixture turns into quinium-246, and the quinium-248 begins to accumulate.Isotest elements, such as CM, have longer half -life, and are more than chemical research than cm and cm.But the probability of spontaneous fission is also increasing.CM has the longest half -life of quinium isotopes (1.56 × 10^), but there is no large amount.This is because the probability of spontaneous fission is more likely by the guidance of the thermal saint.
Which element has the longest half -life of the isotope of Quinium?
Cm
