What type of wave is demurred by radioactive atoms?
There were 3 types of radioactivities: Alpha, Beta, and Gamma. Alpha: Made from 2 protons and 2 neutrons Charge: +2 Mass: 4 Speed: 1/10 the speed of light Ionising power/…Danger: Very High Stopped by: 4cm of air or thick paper Beta: Made from one electron Charge: -1 Mass: 1/1800 Speed: 9/10 the speed of light Ionising power/Danger: Medium Stopped by: 3-5mm aluminium/led Gamma: Is an electromagnetic wave Charge: no charge Mass: 0 Speed: = speed of light Ionising power/Danger: Very low Stopped by: Can't be stopped (unstoppable)
Radio active atoms are alpha, beta and gamma.
There are different types of Radioactivity, ALPHA, BETA and GAMMA Radiation.
Well an alpha radiation particle consists of a helium nucleus, 2 protons and 2 neutrons.
A radioactive atom is an atom that has an unstable nuclear force, and therefore either absorbs or emits a radioactive particle.
beta decay ----- n(udd)->p(uud)+electron+anti-electron neutrino via a W- boson
The atoms that are radioactive are those with unstable nuclei. There is no easy way to tell which is which, so the isotope has to be looked up. All elements have at least so…me radioactive isotopes. There are 36 elements for which all radioactive isotopes are synthetic or fission products, so for practical purposes, there are no radioactive isotopes of them in nature, except where introduced by human activity. They include most of the common elements we find in nature, but not all. There are 44 elements that are found as stable isotopes, but at least traces of radioactive isotopes are found in nature. Among these are hydrogen, carbon, sodium, silicon, chlorine, and potassium, all of which are necessary for life. Radioactive potassium, in particular, is present as 0.012% of all potassium. For another group of elements, including technetium, promethium, and all with atomic numbers of 83 (bismuth) or more, there is no isotope that is stable.
Alpha (the strongest ionizing radiation, but also has the least penetration) Beta (the middle of both ionizing strength and penetration) Gamma (minimal ionizing given the ener…gy level, but most penetration)
Positron Decay of Carbon-11 to Boron-11. Adapted from Types of Radioactivity . The final type of beta decay is known as electron capture and also occurs when ...
When the atomic number increases by one there is either 'beta decay' or the nucleus has captured a positron.
In Noble Gases
Helium is created from the combination of hydrogen atoms fusing together.
