Question

The original radioactive atom, before it undergoes any radioactive decay, is called the [X] atom. When this unstable atom decays, the new atom that is created during the transmutation process is called the [Y] atom. parent, daughter isotope, nuclide alpha, beta cation, anion Radioactive decay of an atom can cause a change in its number of protons. Three of the main types of radioactive decay are alpha (alpha)-decay, beta (beta)-decay, and electron capture (K-capture). Watch the short tutorial on modes of radioactive decay at the site listed below. Then, use the information you learn to answer the following question. Which particle is involved in alpha-decay and is thus known as the alpha particle?_2 He^4_1 H^3 Electron_1 H^2 The reactions involved in nuclear (radioactive) decay are affected by changes in temperature and pressure.

Explanation / Answer

3) parent , daughter

the original radio active atom is called parent element and the decayed product is called daughter element

4) helium
