What are the essential elements that affect life?
Scientists believe that about 25 of the known elements are essential to life.
Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body..
How can we avoid dangerous chemicals?

What element is toxic 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. These toxic metals have no known physiological functions.
What is the most dangerous natural element?
PlutoniumPlutonium: A History of the World’s Most Dangerous Element.
Is chlorine a poisonous gas?
Gaseous chlorine is poisonous and classified as a pulmonary irritant. It has intermediate water solubility with the capability of causing acute damage to the upper and lower respiratory tract. Chlorine gas has many industrial uses, but it was also once used as a chemical weapon in World War I.
Is carbon toxic to humans?
Health effects of carbon Elemental carbon is of very low toxicity. … Chronic inhalation exposure to carbon black may result in temporary or permanent damage to lungs and heart. Pneumoconiosis has been found in workers engaged in the production of carbon black.
Is arsenic a poison?
Arsenic is highly toxic in its inorganic form. Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic. Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions.
What gas kills you instantly?
Carbon monoxide (CO) is a gas that can kill you quickly. It is called the “silent killer” because it is colorless, odorless, tasteless and non- irritating.
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.
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).
What is the most dangerous thing in the world?
Of all the species in the world, the largest—and most dangerous—is the saltwater crocodile. These ferocious killers can grow up to 23 feet in length, weigh more than a ton, and are known to kill hundreds each year, with crocodiles as a whole responsible for more human fatalities annually than sharks.
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 most toxic gas?
nitrogenBut surprisingly, amongst all the toxic, corrosive, and otherwise nasty gases that exist in industry, the most deadly of them all is the one we breathe in the most – nitrogen. Nitrogen (N2) is an inert and invisible gas that makes up about 78% (by volume) of the air we breathe.
What is the oldest element on Earth?
PhosphorusThe oldest chemical element is Phosphorus and the newest element is Hassium. Please note that the elements do not show their natural relation towards each other as in the Periodic system.

Is mercury toxic?
Mercury may have toxic effects on the nervous, digestive and immune systems, and on lungs, kidneys, skin and eyes. Mercury is considered by WHO as one of the top ten chemicals or groups of chemicals of major public health concern.
Which is not toxic element?
Many metals, particularly heavy metals are toxic, but some heavy metals are essential, and some, such as bismuth, have a low toxicity. Most often the definition of toxic metals includes at least thallium, cadmium, manganese, lead, mercury and the radioactive metals.
What element can kill you?
While other toxic metals such as mercury and arsenic kill through the interaction of the metal with the body, polonium kills by emitting radiation which shreds sensitive biomolecules, such as DNA, and kills cells.
What are the harmful elements?
Some elements, such as mercury (Hg), cadmium (Cd), arsenic (As) and chromium (Cr), are toxic or carcinogenic even at low concentrations. Poisoning by exposure to PHEs is well known to affect central nervous system functions, damage blood composition, lungs, kidneys, liver and other vital organs.
What is most expensive element in the world?
rhodiumAs of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium.
What color does plutonium glow?
Radioactive Elements Glow in the dark (ONLY those considered radioactive glow – Uranium glows green, Plutonium glows aqua, Radium glows blue, Radon glows purple, Einsteinium glows blue, Curium glows purple, Phosphorus glows green, Thorium glows orange) by simply exposing them to light or sunlight for a few minutes then …
