Which of the following statements in regarding radiation is true?
a)When α-decay occurs, the atomic mass will decrease but the element will stay the same.
b)Neutrinos have a charge equal to zero and have very little mass; they are detected in α-radiation
c)Electrons edited in β-decay are not orbital electrons , rather produced within the nucleus from a neutron changing into a proton.
d)?-ray carries a positive charge and may occur from a violent collision with another particle.

thank u so much! 6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...
1) Define the following: matter, element, atom, trace element, proton, electron, neutron, atomic number, mass number, isotopes, radioisotope, molecule, compound, salt, ion. 2) List the 6 elements that make up about 99% of the weight of an organism. 3) What are the functions of the trace elements iron, fluorine (fluoride), and iodine? 4) An iodine deficiency can result in goiter. True/False 5) Where are protons, neutrons and electrons located? 6) Can you determine the atomic number and mass number from...
