An Alpha particle, and associated gamma radiation from the excited nucleus.
Yes it does. By the time a radon nucleus has decayed to a stable lead nucleus 6 alpha particles have been emitted. These are dangerous to health. For this reason, basements which are in high radon areas should be positively vented to the outside. Note. care should be taken with decorative granite counter-tops. Some of these cause radon levels in the kitchen which are far above the safe limit.

Radon gas has been linked to potential earthquake predictions as elevated levels of radon gas emitted from the ground have been detected before some earthquakes. However, its effectiveness as a reliable predictor is still under research and not widely accepted.
Element 115, also known as moscovium, is a synthetic element that is highly unstable and rapidly decays into other elements. It is not naturally occurring in nature and its short half-life makes it unlikely to pose a significant danger. However, as with any radioactive material, proper handling and containment are necessary to prevent potential risks.
If the beta particle had been a positron (a positively charged electron), the charge of the new nucleus formed would have been 1 less than the original nucleus. This is because a positron carries a positive charge (+1), whereas a beta particle (electron) carries a negative charge (-1).
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.

If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
People say they have made the element unahexium but hasn't been confirmed and even if there has been and element confirmed its only stable for a few milliseconds before it decays into more stable elements.
It's not. 2He is ridiculously unstable and "immediately" (so fast the decay time has never been measured) decays into a deuteron.
Because radon has no odor or color.
Presuming you mean "Hubble's Law," it is an observed fact that, the further an object is from our Earth, the greater is the red shift of its emitted light. What has been been undeniably observed can only be explained by an ongoing expansion of our Universe.

The junk consists of the remains of the satellites that have been launched from Earth. They have outlived their usefulness and have been abandoned. Eventually their orbit decays and they fall back to Earth. Most will totally burn up due to friction in the atmosphere. Little of it will reach the surface. But it does pose a hazard to the launch of new satellites and spacecraft.
