The ________ constitute(s) most of the volume of an atom

A)neutrons,
B)electron cloud
C)nuclues
D)protons


Please help, thanks!:D

(B) electron cloud

Most of an atom consists of an electron cloud, which is just a region where there is a high probability of finding an electron.

I hope this helps!

Protons and neutrons = nucleus. Electron cloud makes up the bulk of the atom. If the average nucleus was the size of a golf ball, the atom would be the size of a football field (only round). Good luck and may learning be fun!
