<u>Answer:</u> It is so because they have different number of neutrons.

<u>Explanation:</u>

Isotopes are defined as the chemical species which have same number of protons but differ in the number of neutrons.

They have same atomic number but different atomic mass.

<u>For Example:</u>  _6^{12}\textrm{C},_6^{13}\textrm{C}\text{ and }_6^{14}\textrm{C} are the three isotopes of carbon.

The number of protons in all the three isotopes is same which is 6 and the number of neutrons in the three isotopes are 6, 7 and 8 respectively.

Hence, it is so because they have different number of neutrons.

What happens on a molecular level when a diatomic molecule is a gas but is then cooled to a solid?
irina1246 [14]

Answer:

As an example of the processes depicted in this figure, consider a sample of water. When gaseous water is cooled sufficiently, the attractions between H2O molecules will be capable of holding them together when they come into contact with each other; the gas condenses, forming liquid H2O. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass.

Explanation:

Hopefully that helps!
