What does the 1 on hydrogen mean?
The atomic number is equal to the number of protons in an atom’s nucleus.
Hydrogen’s atomic number is 1 because all hydrogen atoms contain exactly one proton..
How old is the Earth in 2020?
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years.
What is the most abundant element in the human body?
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 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 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 most unique element?
The most weird and wonderful elements in the periodic tableKrypton (Atomic number: 36)Curium (Atomic number: 96)Antimony (Atomic number: 51)Copernicium (Atomic number: 112)Bismuth (Atomic number: 83)
What is the world’s most expensive element?
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 is Period 1 called?

What is worth more than gold?
The price of palladium, a precious metal 30 times as rare as gold, has risen by more than 50% since August, surpassing the price of gold for the first time since 2001. This week the price of 1 ounce of palladium topped $1,400, while platinum dipped under $800, and gold hovered just above $1,300.
What element is the heaviest?
uraniumThe heaviest element found in any appreciable amount in nature is uranium, atomic number 92. (The atomic number refers to the number of protons in an atom’s nucleus.)
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.
What is the most expensive thing by weight?
One gram of gold is worth just under $34 per gram. At the top of the list we find a combination of extremely rare metals, radioactive isotopes, and gemstones. The radioactive element Californium, first made in 1950, is the most valuable at $27 million per gram.

What is the coolest looking element?
Liquid helium is literally the coolest element, forming only at -269 degrees Celsius.
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.

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 most useful element?
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 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.
Why is there no element 119?
Ununennium and unbinilium (elements 119 and 120) are the elements with the lowest atomic numbers that have not yet been synthesized. … Even so, the synthesized isotopes still have fewer neutrons than those expected to be in the island of stability.
What is the oldest type of rock on Earth?
zirconsRock Type(s): zircon The Jack Hills Zircon is believed to be the oldest geological material ever found on Earth, dating back to about 4.375 billion years, give or take 6 million years – the zircons are not technically rocks, but we felt that they should be included on this list.
