How does plutonium kill you?
Most forms of plutonium emit alpha particles, which are not very harmful outside the body, but can be very damaging when inhaled. When plutonium particles are inhaled, they lodge in the lung tissue. The alpha particles can kill lung cells, which causes scarring of the lungs, leading to further lung disease and cancer.

Nitrogen – 2.4kg The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
What element makes up 80 percent of the air?
NitrogenNitrogen comprises the greatest part of the atmosphere, at almost 80 percent by volume. Nitrogen is a colorless, odorless, tasteless gas that reacts very little with other substances. The atmosphere also contains oxygen, at about 20 percent.
What elements do not exist on Earth?
Technetium. The first element that was synthesised, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap).
