Alpha particles have two protons and two neutrons. since the atom just lost two protons, it's atomic number decreased two. It also decreased it's mass number by four because it lost two protons and two neutrons.
No, it's the alpha particles which carry away 2 protons. Beta particles are electrons. They can be produced by a number of different routes, but if the beta particle results from the decay of a neutron, then the atomic number increases, since the neutron becomes a proton.
That is called Alpha radiation. The atom ejects what is called an alpha particle which is basically an ionized Helium atom (it doesn't have any electrons). Along with the two protons that the atom emits to change its Atomic Number it also ejects two neutrons which results in its Mass Number decreasing by four.
Yes, because the original nucleus loses 2 protons (also of course 2 neutrons). Thus the atomic number reduces by two and the atomic weight by four
An alpha particle, which is the nucleus of a helium atom.
The number of protons in the nucleus changes.

It's typically called the "Wave-particle duality". And it's easily demonstrated, so it's not "just a theory". If you set up an experiment that will produce results from a wave but not from a stream of particles, a beam of light produces results. So light behaves like a wave. If you set up an experiment that will produce results from a stream of particles but not from a wave, a beam of light produces results. So light behaves like a stream of particles. Whichever one you look for ... waves or particles ... light behaves that way. So, next time someone asks you "Is light a wave or a stream of particles ?", you can answer him confidently, knowing that your answer is the correct one. The correct answer is "Yes ".
Sound energy causes the particles in the medium it is traveling through to vibrate. The medium is a solid, liquid or gas.
excess calcitonin or decreased parathormone
When the body produces decreased levels of aspartoacylase, a build-up of NAA results
vibration of charged particles
the splitting of particles
H+ and Cl-
The number of protons in the nucleus changes.
the molecular particles are changed,
most likely thermal as the more particles move the more heat the object produces.
The region in the nucleus that produces tiny cell particles needed in protein synthesis is the nucleolus. It is responsible for making the small and large subunits of ribosomes.

an alpha particle
The active particles in alkali are calls are positively charged hydrogen ions. When an alkali reacts with an acid, it produces a salt and a water.
