The greenhouse effect occurs when carbon dioxide and other gases prevent heat energy from leaving the atmosphere.

I believe this statement is false. The greenhouse effect occurs when certain gases in the Earth's atmosphere (the air around the Earth) traps infrared radiation. This makes the planet become warmer, similar to the way it makes a greenhouse become warmer.

I hope this helps

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
