2 protons, 2 neutrons
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.
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.
There are 1.51 x 10^16 alpha particles emitted in 1.0 min by a 5.0 mg sample of 226Ra.
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
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.

A proton and neutron are both composed of three quarks. An electron is a fundamental particle and is not composed of smaller particles.

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.
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
the radioacity is due to 232Th decaying to 208Pb. 6 alpha and 4 beta particles.
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.

No. Many atoms do not decay at all. Many that do undergo alpha decay. A few atoms emit neutron radiation.
