It is still called iron.

I think you are correct. The general scientific consensus is that the inner core is under extreme temperature (same as the surface of the sun) and pressure and therefore must be a solid hunk of iron (100km across or something), but I think they've all got it wrong. The net gravity should be zero in all directions at the core and therefore, I would expect the core to be a vacuum, probably not nearly as hot as believed and probably low pressure. I have yet to see a reasonable explanation of why it is thought to be high pressure anyway.
What medium and temperature as there is something called "pressure temperature relationship"
The center of the Earth is an extreme environment. An extremely hot and solid iron core surrounded by a liquid layer of rock comprised of iron and nickel under extreme pressure. No known organisms of any kind or any known materials could survive such extreme temperatures and pressures.
No. Liquid metallic hydrogen only forms when hydrogen is subjected to extreme pressure. Hydrogen is present in trace amounts in Earth's atmosphere in gas form, under low pressure. The core is composed primarily of iron. Liquid metallic hydrogen likely exists in the gas giants Jupiter and Saturn.
The iron is in a crystalline structure under tremendous pressure.
Outer core.
The Earth has an iron core. At the outer core it is so hot that the iron is liquid. At the inner core it is hotter still, but under so much pressure it forces the iron to solidify. Hence: the Earth's core.
The brittle iron broke under the weight of the animal. The sticks were brittle and snapped with little pressure.
The Earth's core is about 1200km thick. it is mostly iron, and is solid due to extreme pressure. The temperature can be up to 7000 degrees.

No. Blood pressure is an actual pressure; it's usually measured in mmHg, but it COULD be measured in kilopascals or pounds per square inch. "Low iron" generally refers to the measurement of a protein called ferritin, and is usually measured in ng/mL.
