What happens to the mass of a radioactive isotope as it decays?
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 is an unstable chemical that decays fast?
H+ ion
What is a fast moving electron given off by a nucleus during radioactive decay and has a negative chare?
its called a beta particle, but its an electron
Are trans uranium elements synthetic?
Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the periodic table after uranium is man-made.
What is the most polar element?
FrF Theoretically it is francium fluoride because the francium has the lowest ionization energy while fluorine has the highest electronegativtey; however, this compound would be hard to study and find in nature for francium is radioactive and very rare. Francium is the largest element found to date. CsF Cesium fluoride would be another highly polar compound for the same reasons as francium fluoride.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.

What is the significance of decay constant?
Physically, the time constant represents the time it takes the system's step response to reach 1-1/e (approx 63.2% of its final value). In radioactive decay the time constant is called the decay constant (λ), and it represents both the mean lifetime of a decaying system (such as an atom) before it decays, or the time it takes for all but 36.8% of the atoms to decay. For this reason, the time constant is reciprocal of mean life.
What is a fast moving electron given off by a nucleus during radioactive decay and has a negative chare?
its called a beta particle, but its an electron
What is a fast-moving electron given off by a nucleus during radioactive decay.?
One part of a beta- particle. The other part is an electron antineutrino
Is a delta particle a fast moving electron given off by a nucleus during radioactive decay?
No, a delta particle is not a fast moving electron given off by a nucleus during radioactive decay. The electron described here is a beta particle, and specifically a beta minus particle. It is given off in (no surprise) beta minus decay. A link to a related question can be found below.
Name 4 thing that affect how fast an organism decays?
temperatures the amount of moisture that wwhat i know it
Is neptunium magnetic?
Neptunium is a chemical element. Atomic Number: 93, Atomic Symbol: Np. Neptunium is fissionable. For this, it is used as fuel in a fast neutron reactor or in a nuclear weapon. Neptunium is not a magnet.
What is released when unstable radioactive nuclei disintegrates?
energy and fast-moving particles are released,
Are trans uranium elements synthetic?
Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the periodic table after uranium is man-made.
Which type of radiation does strontium-90 emit?
Strontium-90 emits beta radiation when it decays. Beta radiation consists of fast-moving electrons.
