Nearly all the elements found in our environment were formed inside stars. The major exceptions are:?

Read your text. Do your OWN homework. Or use a search engine. (But, I'll bet your text will be quicker and more accurate for your purposes.) Spoon-fed information gives one a head full of mush.

And make sure you understand the question before you accept the answers given around here. No one's going to suffer from wrong answers except you, my friend.

Find out what nuclear fusion products are forming throughout a star's life-cycle. A hint: elements which go too far beyond exothermic fusion reactions won't happen inside a star. Remember, I said too far.

D) Hydrogen and Helium which were formed just after the Big Bang. Helium is produced in stars, but the majority in the Universe is "primoridal".

D)

Hydrogen and Helium were produced by the big bang and are used by stars as the "fuel" to create all heavier elements.

i'm not effective if this is a trick question. i imagine the answer is D. Hydrogen, helium, and deuterium were suspected to have existed before the first stars shaped. a megastar fuses hydrogen into helium, and later in existence, fuses helium into heavier aspects. yet can't fuse something into iron. the elements heavier than Iron were shaped in supernova explosions of stars, and were not actually created "interior" of stars (technically).

Hint: which are the lightest of all those elements?

d) a little lithium too.
