The Japanese scientists think they have found the “missing element” within the Earth’s core. The search for the identity element has been going on for decades. It is believed the element makes up a significant proportion of the planet’s core, following iron and nickel.
After recreating the high temperatures and pressure present in the Earth’s inner core, the experiments suggest the missing element is silicon.
Scientists believe silicon makes up 5% of the Earth’s core, which is mainly composed of iron (85%) and nickel (10%).
Other recent experiments suggested that oxygen might also be an important element in the Earth’s core.
