What are the four major elements found in the human body?
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..
What are the 10 most dangerous elements?

Is Dimethylcadmium toxic?
The data showed that, if inhaled, dimethylcadmium was more toxic than the other cadmium non-organic compounds, being a polythropic poisonous substance with particular damaging effects on the kidney, the liver, the CNS and the respiratory organs.
What is a toxic element?
Toxic elements such as mercury, arsenic, cadmium, and lead, sometimes called heavy metals, can diminish mental and central nervous system function; elicit damage to blood composition as well as the kidneys, lungs, and liver; and reduce energy levels.
Is americium man made?
Americium (chemical symbol Am) is a man-made radioactive metal that is solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests. Americium-241 is the most common form of Americium.
How does plutonium kill you?
Because it emits alpha particles, plutonium is most dangerous 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.
What is the deadliest element in the world?
PlutoniumSurely you know what Plutonium is. It’s one of the most dangerous, radioactive, toxic elements in the world. It’s used in atomic bombs and the production of nuclear energy. And it’s responsible for killing a massive number of people in the world, in mere seconds.
Is plutonium man made?
Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
Where is Plutonium Found?
Plutonium generally isn’t found in nature. Trace elements of plutonium are found in naturally occurring uranium ores. Here, it is formed in a way similar to neptunium: by irradiation of natural uranium with neutrons followed by beta decay. Primarily, however, plutonium is a byproduct of the nuclear power industry.
Why isn’t plutonium found naturally?
The reason that plutonium (and other transuranic elements) are so rare in nature is that being radioactive, they decay with a characteristic half-life.
What elements can kill you?
So here is a list of substances that are more poisonous than their LD50 values might indicate.Botulinum toxins. Even though some of them are used in the cosmetic industry (including in botox), the botulinum family of neurotoxins includes the most toxic substances known to man. … Snake toxins. … Arsenic. … Polonium-210. … Mercury.
What elements are dangerous to humans?
Conversely, there are a number of elements that are toxic to the human body, interfere with its functioning and undermine health—such as mercury, lead, cadmium, aluminum, and arsenic.
What is the rarest element?
element astatineA team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What is the strongest poison?
Botulinum toxin1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
