1.11 x 10^10 alpha particles
There are three main types of rays emitted from radioactive elements: alpha particles, beta particles, and gamma rays. Alpha particles have a positive charge, beta particles have a negative charge, and gamma rays have no charge.
If a mixture is electrically neutral, for every alpha particle (which has a charge of +2), there must be two beta particles (each with a charge of -1) to balance the charges. So there are two more beta particles than alpha particles in the balloon.
An alpha particle is composed of two protons and two neutrons.
Beta particles have an electrical charge of -1. Beta particles have a mass of 549 millionths of one atomic mass unit, or AMU, which is about 1/2000 of the mass of a proton or neutron.
The emission of an alpha particle (which is a Helium nucleus) from a radioactive nuclide would decrease its atomic number (z) by two, and its mass number by 4. So for example, Plutonium-239 (z=94) would emit the alpha particle and jump back down the table to Uranium-235 (z=92). It is possible to go up the table (increase atomic number) through certain beta decays.
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.

Atomic number of radium is 88 and that of bismuth is 83. So atomic number is to be reduced by 5. But as alpha is emitted atomic number reduces by 2. So a beta decay is needed which would increase the atomic number by 1. So 3 alpha decay and one beta decay would make radium into bismuth

Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
Alpha radiation consists of alpha particles, which are helium nuclei composed of 2 protons and 2 neutrons. Since neutrons do not carry an electrical charge, alpha particles have a net charge of +2, meaning they have 2 electrons.
If the soil sample has 30 million particles of soil and 60 of those particles are sand, then the number of soil particles that are sand is 60. Sand particles represent 0.000002% of the total particles in the soil sample.
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
the radioacity is due to 232Th decaying to 208Pb. 6 alpha and 4 beta particles.
An alpha particle is composed of two protons and two neutrons.
Many particles can be emitted from radioactive decay. We have Internal Conversion in which a nucleus transfers the energy to an electron which then releases it. There is also Isometric Transition which is basically the gamma ray (photon). There is the decay in which a nucleon is emitted. In this scenario we can have an alpha decay (in which an alpha particle decays), a proton emission, a neutron emission, double proton emission (two protons are emitted), spontaneous fission (the nucleus brakes down into two smaller nuclei and/or other particles) and we have the cluster decay (where the nucleus emits a smaller nucleus). There is the beta decay too. There is the Beta decay (electron and electron antineutrino are emitted), positron emission (a positron and an electron neutrino are emitted), electron capture (an electron is captured by the nucleus and a neutrino is emitted), bound state beta decay (the nucleus decays to an electron and an antineutrino but here the electron is not emitted since it is captured into a K-shell), double beta decay (two electrons and two antineutrinos are emitted), double electron capture (the nucleus absorbs two electrons and emits two neutrinos), electron capture with positron emission (an electron is absorbed and a positron is emitted along with two neutrinos), and double positron emission (in which the nucleus emits two positrons and two neutrons).
Beta particles have an electrical charge of -1. Beta particles have a mass of 549 millionths of one atomic mass unit, or AMU, which is about 1/2000 of the mass of a proton or neutron.
