Radon-219 decays to radon-218 by releasing... a. a positron b.a muon O c. a neutron O d. an electron O e. a proton
MrRa [10]

Answer: Option (c) is the correct answer.

Explanation:

A positron is denoted as ^{0}_{+1}e, a neutron is denoted as ^{1}_{0}n, an electron is denoted as ^{0}_{-1}e, and a proton is denoted as ^{1}_{1}p.

Therefore, when ^{219}Rn will decay into ^{218}Rn this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.

The reaction will be as follows.

                ^{219}Rn \rightarrow ^{218}Rn + ^{1}_{0}n

Which factor is generally responsible for high melting points?
kherson [118]
The factor that is generally responsible for higher melting point is intermolecular forces. The compounds that are covalent in nature are made of molecules rather than ions. It has been seen that some of the covalent compounds have polar molecules at one end, due to which the one end has more electronegative force than the other. The electrostatic force that is bounding the compound is the main cause of higher melting point of this compound.  So it is true that with the increase of polarity of a compound creates higher melting point. .. hope I helped
