Types of Radioactive Decay| Questions with 100 % Correct Answers | Verified

Why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? - Chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes. Nuclear reactions involve changes to protons and neutrons in an atom; isotopes differ in neutrons, and so they react differently to these changes. Isotopes behave similarly in - chemical reactions __________ involve only a rearrangement of electrons, and do not involve changes in protons or neutrons. - chemical reactions In __________ a large amount of energy is released or absorbed. - nuclear reactions New elements can be formed as a result of __________ - nuclear reactions Exothermic and endothermic reactions can occur during - both chemical and nuclear reactions Which would result in radioactive decay? - a neutron-to-proton ratio of 1:2 in a large nucleus a nucleus that contains 90 protons and 100 neutrons any isotope of the element uranium, which has atomic number 92 Which type of radioactive decay produces particles with a positive charge and very small mass? - beta Which type of radioactive decay produces radiation with zero mass? - gamma
