The spectrum of the Sun is primarily the continuous emissive one of a 
“black body” at a surface temperature of 6500K or thereabouts.

Superimposed on that are absorption lines corresponding to a range of 
elements, representing cooler substances in the surrounding “photosphere”, 
I think it’s called.

Which of these lines do you think is characteristic of this mythical 
“liquid metallic hydrogen” of yours?

Fun fact: originally it was thought that those lines in the spectra of the 
Sun and other stars were characteristic of the entire makeup of the bodies 
concerned. In other words, they were full of elements much like those that 
make up the Earth and other planetary bodies.

A young doctorate student named Cecilia Payne, after some careful study, 
came to the remarkable conclusion that stars were mostly hydrogen and 
helium, and these spectral lines were due, in effect, to relatively small 
amounts of contaminants in among that bulk of hydrogen and helium.

What “impacts on the sun surface”?
