The result is that the nucleus changes into the nucleus of one or more other elements. decay example sentences. To decay is defined as to rot, lose strength or deteriorate. They're higher density materials that lack all the little pockets of air you find in a porous material. Examples include plastic, glass, and metal. For example deuterium is an isotope of hydrogen that is not radioactive . A radioactive element is one with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element.

In general a solid will undergo sublimation, thereby avoiding the liquid phase, if the temperature and pressure are below the triple point; ie, when only the vapour and solid can co-exist. These daughter nuclei have a lower mass and are more stable (lower in energy) than the parent nucleus. SCIENCE 4 Materials That Undergo DecayQuarter 1 Week 3Hello kids!
