In reality, as the atoms gets decayed it gives out radiations such as alpha, beta and Gama. Alpha is a helium nucleus which is massive and beta is electron but fast moving and Gama is an electromagnetic radiation. So as the atom decays then its mass is likely to be reduced.
Rutherford's radioactive law deals with the number of atoms undecayed present at an instant 't' given in the form N = No e-lambda t
Here No is the total atoms present both decayed and undecayed in a sample.
N is the number undecayed present
lambda - the decay constant
t - the time elapsed
What else can I help you with?
What is a parent isotope?
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
What is the mass of the isotope 195Au?
195Au is an isotope of gold with a half life of about 186 days. It decays into 195Pt, an isotope of platinum. Its mass is 194.97 atomic mass units.
What is the atomic mass of roentgenium?
The atomic mass of the most stable isotope of Roentgenium is 281. This most stable isotope decays in around 36seconds. Oddly, it's most stable isotope has the same atomic mass as the most stable isotope of the element before: Darmstadtium.
How do you identity a daughter isotope?
A daughter isotope is identified by its distinct atomic number and mass number resulting from the decay of a parent isotope. The transition typically involves the parent isotope undergoing radioactive decay, which alters its nuclear structure. To identify the daughter isotope, one can analyze the decay chain and utilize techniques such as mass spectrometry or radioactive dating methods. Additionally, the half-life and decay products can help confirm the specific daughter isotope formed.
What happens to the atomic mass number in a radioactive substance?
In a radioactive substance, the atomic mass number may change as a result of radioactive decay. During radioactive decay, radioactive atoms undergo nuclear reactions, which can lead to the emission of radioactive particles such as alpha or beta particles. These emitted particles can cause a change in the number of protons and neutrons in the nucleus, resulting in a different atomic mass number for the resulting atom or isotope.

In a time equal to two half-lives of a radioactive isotope would you expect all of that isotope to have decayed?
No. In two half-lives, a radioactive isotope will decay to one quarter of its original mass. In one half-life, one half of the mass decays. In the next half-life, one half of the remaining mass decays, and so on and so forth. At each half-life point, you would see 0.5, 0.25, 0.125, 0.0625, etc. remaining. The logarithmic equation is... AT = A0 2(-T/H)

What does the symbol PO-210 represent?
The symbol Po-210 represents the radioactive isotope of polonium with an atomic number of 84 and a mass number of 210. Polonium-210 is a highly toxic substance that emits alpha particles during radioactive decay.
What is the atomic mass of roentgenium?

What element has a mass of 190?
Iridium has an atomic mass of 192 (192.217)
When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.

Radiocarbon is a type of?
Radiocarbon or Carbon-14 is an isotope of the element carbon. It is used extensively in archeology for dating artifacts. It can date carbon artifacts for upto 60,000 years. C-14 decays to non radioactive nitrogen-14 with half life of 5730 years.
