What elements are toxic to the human body?
Genetic Effects on Toxic and Essential Elements in Humans: Arsenic, Cadmium, Copper, Lead, Mercury, Selenium, and Zinc in Erythrocytes..
What is the most useful element on the periodic table?
carbonAnd so we are left with carbon, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.
What is the most dangerous element?
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.
What is the weakest element?
Diamond is the hardest known natural substance and for that reason it is often used in drill bits. For the weakest element, I would probably go for helium – one of the noble gases. It is very light and unreactive.
What element is the most powerful?
1 Air/wind. Air control is the most strongest element there is. 2 Fire. Fire is a really strong element and this sounds brutal but you can burn down bad people’s houses and burn people you don’t like….What is the best Zodiac element?SignElementQualitiesLeoFireHot & DryVirgoEarthCold & Dry2 more rows

What element can kill you?
Polonium-210 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.
How fast can plutonium kill you?
5 grams of plutonium to die immediately, compared to about . 1 grams of cyanide. The plutonium at Fukushima isn’t in the air, but inhaling about 20 milligrams of plutonium would probably kill you within a few months. External exposure carries almost no risk.
Why is space black?
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Are there any elements only found in space?
Technetium was made in the laboratory back in the 1930s, but was first discovered in these giant stars in 1952, the only naturally occurring place in the Universe where it’s been discovered in any sort of large abundance.
Where does hydrogen come from in the universe?
Hydrogen is found almost everywhere in the universe. It occurs between and within stars, and in the enormous gas and dust clouds that exist throughout interstellar space. Scientists have known since the 1970s that bonds between hydrogen atoms form on the very cold surface of interstellar dust grains.
Which 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 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).
