Dear all,
can you help me, please?
If I want to describe the atom, should I say:
a) the atom is made up of electrons, neutrons and protons          or
b) the atom is made of electrons, neutrons and protons?

are they both possible?
thank you,

I prefer a) made up. It implies that there is more than one component, whereas I don īt think just īmade of ī does.

I īd prefer consists of but since there īs no such option I would also go for is made up of.

I agree with Sophia on both points. We wouldn īt use "made of", because that is closer in meaning to "made from", meaning the parts that go into making a product. We don īt "make" or "build" an atom, so it isn īt "made of" anything. It consists of (or is made up of) protons, neutrons and electrons.
