Answer:
a negative ion, and an isotope.
Explanation:
The perfect atom consists of an equal balance in all 3. If the neutrons are not even with the protons, it is an isotope since it is like another version of the so called (but not actually) 'perfect' atom. If there is more electrons, the charge is negative, making it an ion.
Answer: A curve showing the relationship between temperature and time for a given amount of liquid heated at constant rate is a heating curve.
This is the option a. heating.
The increase of temperatue as result of heating may be ploted to show the changes. This increase of temperature related with the heat depends of the heat capacity of the substance. For a fixed amount of heat, substances with high heat capacity exhibit a lower increase in temperature than substances with low heat capacity.

Correct Answer:
Option D i.e. CH3CH2CH2CH2CH3
Reason:
Isomers are the compounds having same molecular formula, but different structural formula.
The molecular formula of the compound is C5H12
The compound present is question (i.e. 2-methyl butane) and option D (n-pentane) has same molecular formula. Hence, they are isomers.However, compound present in option A, is the same compound provided in question. Hence, it is not an isomer. Compounds reported in option B and C has one carbon atom less and more, respectively as compared to the compound reported in question. Hence, they are also not isomers.
