Molecules are farthest apart in a gaseous state and closest together in a solid state. Liquid state is in the middle. Just think of the things you encounter everyday, you can't move your hand through a desk because it is comprised of molecules that are held so close together through various forces and molecular interactions.
<u>Answer:</u> The correct answer is Option 2.
<u>Explanation:</u>
Radioactive substances are unstable in nature and tend to get stable by some nuclear reactions.
Nuclear reaction are the reactions which changes the nucleus of an atom. There are two nuclear reactions: Nuclear fission and Nuclear fusion.
These two processes can make a radioactive sample can convert it into a non-radioactive sample.
Nuclear fission reactions: In these reactions a larger nuclei (parent nuclei) splits into two or more stable daughter nuclei.
Nuclear fusion reactions: When two or more smaller nuclei combine to form one larger nuclei, these reactions takes place.
In the question, it is asked the characteristic of a non-radioactive daughter isotope after it is formed from a parent isotope. The parent isotope is undergoing nuclear fission reaction and is forming a stable nucleus.
Hence, the correct answer is Option 2.
The full ionic equation for the conversion of aqueous lead (II) nitrate to solid lead (II) sulfate and aqueous potassium nitrate is as follows:
<h3>What is
ionic equation ?</h3>
PbSO4(s) + 2 K+ + 2 NO3 = Pb2+(aq) + 2 NO3(aq), 2 K+(aq), and SO42(aq) (aq)
Let's look at the molecular formula that results in solid lead (II) sulfate and aqueous potassium nitrate when aqueous lead (II) nitrate and aqueous potassium sulfate interact. This reaction involves two displacements.
PbSO4(s) + 2 KNO3 = Pb(NO3)2(aq) + K2SO4(aq) (aq)
All ions and molecular species are included in the full ionic equation.
PbSO4(s) + 2 K+ + 2 NO3 = Pb2+(aq) + 2 NO3(aq), 2 K+(aq), and SO42(aq) (aq)
The full ionic equation for the conversion of aqueous lead (II) nitrate to solid lead (II) sulfate and aqueous potassium nitrate is as follows:
PbSO4(s) + 2 K+ + 2 NO3 = Pb2+(aq) + 2 NO3(aq), 2 K+(aq), and SO42(aq) (aq)

Answer:
See explanation
Explanation:
The degree of movement of molecules in each not the three different states of matter depends on the arrangement of the molecules.
In a solid, molecules are packed closely together and are held in fixed positions by strong intermolecular forces such that they can only vibrate or rotate about a fixed point.
In liquids, molecules are less closely packed hence they can flow around each other but possess only little kinetic energy. Intermolecular forces in liquids are much lesser than that of solids.
In gases, intermolecular forces are negligible and gas molecules move with a very high velocity and possess high kinetic energy. There are large spaces between gas molecules and they are always in motion.
