Yes, daughter element has atomic number two units less and Atomic Mass four units less.
The two elements that undergo alpha decay are uranium and thorium.
This process is known as alpha decay. During alpha decay, an unstable atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This emission results in the transformation of the original nucleus into a new, lighter element with a lower atomic number.
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.
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.
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.
Alpha decay
Alpha decay
This is an example of alpha decay.
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.
a new element is formed
When uranium undergoes radioactive decay, it releases alpha, beta, and gamma radiation. This breakdown process results in the transformation of uranium isotopes into different elements, known as its decay chain. This chain typically includes elements such as radium, radon, and lead, each with its own unique radioactive properties and emissions.
