Question

What combines to form compounds?

A.
atoms of elements

B.
molecules

C.
minerals

D.
valences

Answer 1

I think it's either A or D.

Answer 2

No B

Answer 3

Whatever sorry........

Answer 4

Arguably, A, B, and C are all logical answers.

Chemical reactions can involve both pure elements and molecules. Minerals are simply complex molecular compounds, so they fall under this category.

Valences, however, are unrelated- they're the electron configurations of atoms.

If you have to pick just one answer, I would say it's A. All chemical reactions involve atoms.

Answer 5

Omg r u serious

Answer 6

Wow..

Answer 7

D was the right answer I found it online

Answer 8

You could say that the valences electrons of atoms merge to form compounds, since covalent compounds do share their electrons.

This isn't quite the case for ionic compounds, though. I seriously doubt D is correct- if it is, then it's a rather poorly worded question.
