Q. Which element used for Oxygen transport?
Solution:
- Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26.
- It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core.
- It is the fourth most common element in the Earth’s crust.
- Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space.
