What happens during radioactive decay answers? After beta decay the atom has charge +1.  An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons. Gamma rays are often emitted during beta decay as well. Beta-decay or β decay represents the disintegration of a nucleus to become a daughter through beta particle emission. ∙ 2012-10-13 17:54:43. In positron emission, the atomic number Z decreases by one while the mass number A remains the same. The electron with high velocity is emitted out of the nucleus and its mass is 1/1836 units. Here, the mass of the daughter nucleus remains constant, and a different element is formed. B) The mass number decreases by 4 and the atomic number decreases by 2. Also, electron has a negative charge, and thus the charge of particle emitted during beta minus decay is -1. 2. How will beta decay affect the atomic number and mass number of the atom? Nice work! For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is . So the mass # is 0, but the atomic # is +1. d. Alpha decay is usually restricted to the heavier elements in the periodic table. The example used in this experiment is: Cs137!Ba137 + e + e The neutrino was postulated in 1931 by Pauli to explain how in beta decay the following could be conserved: B. What happens to the mass number during beta decay?
