Pls help! Polonium has a large, unstable nucleus. Through which process is it most likely to become stable?
2 answers:
The process through which Polonium is most likely to become stable is: B. alpha decay.
An unstable element refers to a chemical element that lose particles because its nucleus contain an excess of internal energy (neutron or proton).
This ultimately implies that, an unstable element is radioactive in nature.
In Science, some examples of an unstable element are:
- Tritium.
- Bismuth-209 .
- Xenon.
- Polonium.
Polonium is a chemical element with a large, unstable nucleus.
Basically, the most stable isotope of Polonium is Polonium-209, which typically undergoes an alpha decay to form lead-205 and the emission of an alpha particle.
⇒ ---->
In conclusion, we can deduce from the above chemical equation that Polonium is most likely to become stable through an alpha decay.

Answer: The boiling point of water at 81 kPa will be 298.17 K.
Explanation:
The boiling point of water is 373 K at atmospheric pressure. So, to calculate the boiling point at 81 kPa, we use the law given by Gay-Lussac.
Gay-Lussac Law states that pressure is directly proportional to the temperature when volume and moles remain constant.
Mathematically,
where,
= Initial pressure and temperature
= Final pressure and temperature
We are given:
Putting values in above equation, we get:
Hence, the boiling point of water at 81 kPa will be 298.17 K.
Answer:
The correct answer is option a.
Explanation:
Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in ().
J = diffusion flux
A = Unit area A through which atoms moves.
M = mass of atoms passes in t interval of time.
