What do we call the area of
an atom where electrons are
located?
a. nucleus
b. electron cloud
c. mitochondria

B. Electron Cloud

Explanation:

It would not be A because, electrons orbit the nucleus so they cannot be physically IN it.

It cannot be C either because, we are talking about an atom not a cell. Mitochondria is only present in cells.

i am going to guess that it is co2.

looks like the answer is     c     to me!
