If all you ever do is smoke bong hits, try using vaporizers, extracts, tinctures, or marijuana edibles (otherwise known as medibles). Vary how, when and with what you dose yourself. Vaporizers open up a whole new world of marijuana effects that you canât get when smoking whole marijuana. Care for your brain.
What happens when an atom emits an alpha particle or beta particle? alpha: 2 protons & 2 neutrons leave nucleus as a helium nucleus. This results in the atomic mass decreasing by 4 units and the atomic number decreasing by 2 units.
Many heavy nuclei emit an energetic alpha particle when they decay. For instance uranium-238 decays into thorium-234 with a half-life of almost 4.5 billion years by emitting an alpha particle: The mass number of uranium-238 declines by four and its atomic number by two when it emits an alpha particle.
