The diagram shows four different locations in an atom.
a shaded circle is shown, labeled nucleus. two small points labeled two and three are shown inside this shaded circle. a lighter shaded concentric circle is shown with a radius more than double the radius of the inner circle. a point labeled one is shown inside a section of this circle which does not overlap with the inner circle. a flower petal like shaded region is shown above and below these circles. a point labeled four is shown inside the lower petal.
which locations are likely to have subatomic particles with the least mass? (3 points)
group of answer choices
1 and 2
2 and 3
1 and 4
3 and 4

1 and 4

Explanation:

In the figure attached, a plot of the problem is shown.

Location 1 and 4 are likely to have subatomic particles with the least mass because they are not in the nucleus, which is the location with most of the mass of the atom.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
