What is a product of the beta decay of 98mo?
3.6. Technetium-99 is prepared from 98Mo. Molybdenum-98 combines with a neutron to give molybdenum-99, an unstable isotope that emits a β particle to yield an excited form of technetium-99, represented as 99Tc*.
What is positive beta decay?
Atoms emit beta particles through a process known as beta decay. One type (positive beta decay) releases a positively charged beta particle called a positron, and a neutrino; the other type (negative beta decay) releases a negatively charged beta particle called an electron, and an antineutrino. …
What is beta decay example?
The decay of technetium-99, which has too many neutrons to be stable, is an example of beta decay. A neutron in the nucleus converts to a proton and a beta particle. The nucleus ejects the beta particle and some gamma radiation. The new atom retains the same mass number, but the number of protons increases to 44.
Is alpha emission the same as alpha decay?
Alpha particles are subatomic fragments consisting of two neutrons and two protons. Alpha decay occurs in elements with high atomic numbers, such as uranium, radium, and thorium. The nuclei of these elements are rich in neutrons, which makes alpha particle emission possible.
What is the alpha decay of radon 198?
polonium-194
The alpha decay of radon-198 yields polonium-194. The atomic number of radon is reduced by 2 protons so it changes from 86 to 84.
What do you mean by isotopes and isobars?
Isotopes are atoms with the same number of protons but differing numbers of neutrons. Isobars are atoms of different chemical elements having equal values for atomic mass. Isotopes have the same atomic number. Isobars have different atomic numbers. Isotopes have a different atomic mass.
What is an isotope in simple terms?
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
How are isotopes used in real life?
Among such prevalent uses and applications of radioisotopes are, in smoke detectors; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
