Alpha particle is composed of two protons and two neutrons (equivalent to He nucleus). So the parent decaying by alpha decay results in a daughter having atomic number less by two and mass number less by four.

Which two elements undergo alpha decay?

The two elements that undergo alpha decay are uranium and thorium.


Into what elements does uranium 235 decay?

Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.


What is the alpha decay of calcium 42 equation?

There is no equation. Calcium-42 is stable and does not decay. Calcium is also much to light for alpha decay, which requires elements heavier than nickel, so no isotope of calcium undergoes alpha decay.


Which phrase describes one characteristic of radioactive elements?

Radioactive elements undergo spontaneous decay, emitting radiation in the form of alpha, beta, or gamma particles.


What do unstable isotopes become when they decay?

Unstable isotopes become more stable isotopes or different elements when they decay through processes such as alpha or beta decay. The decay results in the emission of radiation in the form of alpha or beta particles and gamma rays.


What is the name of the elements that have the atomic number over 95?

All these elements are raidoactive, and will decay with the emission of alpha, beata or gamma radiation.

In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?

No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.


In alpha and beta decay the parent elements is always a different element from the daughter element?

true


Can alpha and beta decay the parent element and the daughter element can be different isotopes of the same elements?

False.


How were Alpha decay and beta decay discovered?

Alpha decay was discovered in 1899 by Ernest Rutherford, who observed that certain radioactive elements emitted alpha particles. Beta decay was discovered in 1896 by Henri Becquerel and later studied by Ernest Rutherford and others, who noticed that certain radioactive elements emitted beta particles. These discoveries were important in understanding the nature of radioactivity and led to further research in nuclear physics.


Who discovered radioactive decay in 1898?

ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
