假设“half life”是指科学中的“半衰期”概念,那么它通常应用于物理学、化学、生物学等领域,特别是在讨论放射性物质衰减、药物代谢或生物分子稳定性时。 造句例句: 中文:半衰期是描述放射性元素衰变速度的一个重要参数。 英文:Half-life is an important parameter describing the deca...

When one hears the phrase “half-life”, many people think of the popular video game of the same name, but anyone who has ever read about nuclear power, weapons, storage or waste will likely realize that it is related to radioactive elements. Scientists measure the half-life of a substan...
Half-Life formula You can find the half-life of a radioactive element using the formula: wheret1/2is the half-life of the particle,tis the elapsed time,N0is the quantity in the beginning, andNtis the quantity at timet. This equation is used in the calculator when solving for half-life...
Marie Skłodowska Curie, the Polish-French chemist discovered both radioactivity and the radioactive elements radium and polonium, achievements that won her two Nobel prizes. Time Life Pictures/The LIFE Picture Collection/The LIFE Picture Collection/Getty Images ...
Radioactive Decay (Half Life) Equation Every element has a nucleus made up of a distinct number of protons and neutrons that sit in the center of the atom and make up most of an elements mass. While each element has a specific nucleus, they are not always stable. When elements have ...
A radioisotope's half-life, or the amount of time it takes one half of a radioisotope's atoms to decay, is a very useful measure to know. Radioactive elements tend to be on the last row of the periodic table, and the last row of the rare earth elements. Radioactive Decay Radio...
HALF LIVES half-life: 1: the time required for half of something to undergo a process: as a: the time required for half of the atoms of a radioactive substance to become disintegrated b: the time required for half the amount of a substance (as a drug, radioactive tracer, or pesticide...
Radioactive Decay and Half Life Decay happens in pairs. One element decays to another, more stable element. As one decreases, the other increases Ex: C14 decays into N14 4. The half-life of each element is constant. It’s like a clock keeping perfect time. Now let’s see how we can...
Half Life of Radioactive Atoms The half-life of an element is the time it takes for half of the material you started with to decay. 2. Each element has it’s own half-life Each element decays into a new element 4. The half-life of each element is constant. It’s like a clock ke...
