In summary, anti-hydrogen looks identical to normal hydrogen, and a visible molecule composed of anti-matter would have the same optical properties as a molecule of normal matter.

I am curious as to how a single anti-matter atom looks, say anti-hydrogen. Further, Assuming you had the resources what would a visible (to the naked eye) molecule look like?

google positronium, a hydrogen like atom composed of an electron and a positively charged antiparticle of the electron.

Anti-hydrogen has negatively charged nucleus (anti-proton) and positively charged particle (positron) orbiting around it. Supposedly it's spectrum should be exactly the same as the one from normal hydrogen, which would confirm something known as CPT symmetry. The color (or transparency) of macroscopic objects is due to their absorption and emission of the photons of visible light (an object is transparent if it doesn't absorb photons of visible light; they just pass through it, into our eyes). If there is a symmetry between matter and antimatter, a macroscopic object composed of anti-matter should have the same optical absorption and emission spectrum (I guess) and therefore it should have the same color (or remain transparent).
 

FAQ: Anti-Matter Atom & Molecule Appearance: I'm Curious!

1. What is anti-matter and how is it different from regular matter?

Anti-matter is a type of matter that has the opposite charge and spin compared to regular matter. This means that anti-matter particles have a positive charge instead of a negative charge, and rotate in the opposite direction. When matter and anti-matter come into contact, they annihilate each other, releasing a large amount of energy.

2. How is an anti-matter atom or molecule formed?

Anti-matter atoms and molecules are formed through high-energy collisions, such as those that occur in particle accelerators. When matter particles collide with their anti-particles, they can form anti-matter atoms and molecules. These are unstable and typically only exist for a short period of time before annihilating with regular matter.

3. What do anti-matter atoms and molecules look like?

Since anti-matter atoms and molecules are essentially the same as their regular matter counterparts, they look very similar. However, because they have opposite charges, they would appear to have a reversed orientation. For example, an anti-hydrogen atom would have a positron (anti-electron) orbiting an antiproton, while a regular hydrogen atom has an electron orbiting a proton.

4. How do scientists study anti-matter atoms and molecules?

Studying anti-matter atoms and molecules is a difficult task because they are highly unstable and only exist for a short period of time. Scientists use particle accelerators to create and study these particles, as well as advanced technology such as magnetic traps to contain them. They also study the energy released during annihilation to gain information about anti-matter.

5. Could anti-matter atoms and molecules be used for practical applications?

While anti-matter has been used in scientific research and experiments, it is currently not practical for everyday use due to the high cost and difficulty of creating and containing it. However, scientists continue to study anti-matter in hopes of finding potential uses in fields such as energy production and space travel.
