Using the periodic table and your knowledge of atomic structure. compare the number of electrons in a carbon-12 and carbon-14 isotope.

They both carbon 12 and carbon 14 have the same number of Electrons but the difference is carbon 14 has more neutrons.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.

The right answer is b hydrogen bonds!
