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.
It's theorized that the deep interiors of gas giant planets like Jupiter may be mainly liquid metallic hydrogen.
Saturn, Jupiter and other gas giants most likely contain liquid and metallic hydrogen
No known planet has a core of metallic hydrogen, but Jupiter and Saturn have layers of liquid metallic hydrogen surrounding their cores.
Only the Earth is known to have a core that includes liquid metal.However, Jupiter and Saturn do have regions composed of metallic liquid hydrogen. Also, there is some evidence that Mercury and Venus may have liquid metal in their cores. Mars may have some liquid metallic sulfide in its core.
Jupiter is a very massive planet composed mostly of hydrogen. It is massive enough that below a certain depth the pressure from the overlying layers is enough to convert the hydrogen into its liquid metallic state.
Saturn
Gaseous on the outside, then liquid hydrogen, more dense metallic hydrogen, rocky core
The metallic region is between the inner and outer core of the Earth; contain iron and nickel.
Saturn
It's core has a surrounding layer of liquid metallic hydrogen
Jupiter is a very massive planet composed mostly of hydrogen. It is massive enough that below a certain depth the pressure from the overlying layers is enough to convert the hydrogen into its liquid metallic state.
Jupiter doesn't have a crust, it is made of gas. The core is theorized to be an inner layer of liquid metallic hydrogen surrounded by an outer shell of regular liquid hydrogen.
