Why does a sample of a radioactive element tend to lose mass gradually?
Wiki User
∙ 6y ago
It actually loses very little mass due to the release of beta particles (electrons and positrons) as the element undergoes radioactive decay. But the loss of alpha particles (He nuclei) represents considerable loss of mass. Depending on the element, the time scale for the loss of mass can vary enormously, from fractions of a second to thousands of years.

How is half time used on an element?
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.
Half-life use in a sentences?
A Half-Life is half the time it takes for a radioactive element or a drug to lose its How_do_you_use_half_life_in_a_sentenceor change into something else.
Some atoms such as carbon-14 whose nuclei are not stable lose parts of their nucleus through decay -In the process they become another element -Atoms such as this are said to be?
Radioactive.
A 100 gram sample of a radioactive element is present at 9 a.m. on Monday and only 25 grams of the element can be detected at 9 a.m. on Friday. What is the half-life of the source?
The half-life is 2 days. You start with 100 grams. In one half life, you will lose 50 grams and have 50 grams remaining. In a second half-life, you will lose 25 of the 50 grams and have 25 grams left. You will have lost 75 grams of a 100 gram sample of radioactive material and have only 25 grams of it left after two half-lives. That means there are two half-lives from 9 a.m. Monday to 9 a.m. Friday. That's 4 days for 2 half-lives, or 2 days for one half-life.
What is a nonradioactive material?
A non-radioactive element is an element that has at least 1 isotope that is not radioactive. The means that at least one isotope has a stable nucleus that does not break down by shooting off high-energy particles.
Are radioactive isotopes produced when atoms lose electrons?
When atoms lose electrons cations are produced.
Process by which unstable nuclei lose energy?
Radioactive decay
Why does a PC gradually lose its original Performance?
A PC can gradually lose its original performance because of malware, viruses, and unused registry code lurking around. Cleaning your system will improve its performance.
Why do different atoms gain or lose neutrons?
poker. ^ Poker? i don't think elements have much interest in card games.. atoms lose neutrons due to radioactive decay, these atoms exist as different isotopes of the same element. Carbon-12 and carbon-14 both exist as the same element (atomic number 6), but with different atomic mass and number of neutrons.
How do airplanes land on the ground?
They slow down gradually and lose height as they land
Can you lose muscle?
Yes, if muscles aren't used much, they gradually get smaller.
If a 100 g sample of a radioactive element decays to 25 g in 4 days what is the half-life of the element?
If a radioactive sample contains 1.25g of an isotope with a half-life of 4.0 days, then 0.625g (1/2) of the isotope will remain after 4.0 days, 0.3125g (1/4) after 8.0 days, 0.15625g (1/8) after 12.0 days, etc. AT = A0 2(-T/H)
