What are four natural radioactive series give the decay series of all four?

The four most common modes of radioactive decay are: alpha decay, beta decay, inverse beta decay (considered as both positron emission and electron capture), and isomeric transition. Of these decay processes, only alpha decay changes the atomic mass number (A) of the nucleus, and always decreases it by four.

How many radioactive series are there?

four radioactive series
2.1. The basic natural radioactive elements are included into four radioactive series as shown in Table I. These are: thorium series, neptunium series, uranium series and uranium-actinium series. All of radioactive series articles are bond by irreversible reciprocal transformations.

What are the 4 types of nuclear emissions decay modes?

17.3: Types of Radioactivity: Alpha, Beta, and Gamma Decay

• Alpha Decay.
• Beta Decay.
• Gamma Radiation.

Why is uranium called 4n 2?

The uranium-series begin with Uranium – 238 and undergoes a series of Alpha and Beta decays until a stable nucleus is obtained which is lead- 206 in this series. The mass number of members of this series when divided by 4 gives the remainder 2. That’s why the series is called (4n + 2)

What do you know about four radioactive series?

radioactive series, any of four independent sets of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. The fourth set, the neptunium series, is headed by neptunium-237, which has a half-life of 2,144,000 years. …

Why is lead 206 stable?

Lead-206 is a stable isotope because it will not decay into a different element (non-stable isotopes will undergo radioactive decay and change into a…

What are daughter isotopes?

In nuclear physics, a decay product (also known as a daughter product, daughter isotope, radio-daughter, or daughter nuclide) is the remaining nuclide left over from radioactive decay. Radioactive decay often proceeds via a sequence of steps (decay chain).

What is the daughter element of uranium?

A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234.
