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 is the most abundant element in the human body?
Oxygen
is the most common element in the human body, comprising approximately 65.0% of body mass. Most of the oxygen present is found in the form of water.
What are the three most abundant elements?
The top three most abundant elements on Earth in terms of quantity of atoms are:
oxygen, silicon, and aluminum
(in that order). In terms of total mass, iron is the most abundant element on Earth.
What are the 5 most common elements on Earth?
The mass-abundance of the nine most abundant elements in the Earth’s crust is approximately: oxygen 46%,
silicon
28%, aluminum 8.3%, iron 5.6%, calcium 4.2%, sodium 2.5%, magnesium 2.4%, potassium 2.0%, and titanium 0.61%. Other elements occur at less than 0.15%.
What is the rarest element in the universe?
Astatine
is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later. Decades after its discovery, very little is known about astatine.
Why is there gold in the human body?
The actual point of human body containing Gold has recently been determined. It plays a vital role in health and maintenance of the joints. Also, being

totally 100% true
: nearly all the elements in the human body were made in a star and many have come through several supernovas. …
Which metal is found in human body?
The remaining two and a half percent of your body are largely metals −
sodium, potassium, magnesium, calcium, manganese, iron, cobalt copper, zinc, and molybdenum
− and despite their relatively low total mass, these elements are just as important as the first 97.5%.
Which metal is found most in Earth?
Aluminum
is the most abundant metal in the Earth’s crust, and the third most abundant element therein, after oxygen and silicon. It makes up about 8% by weight of the Earth’s solid surface. Earth’s crust occupies less than 1% of Earth’s volume. Oxygen is 46.6% , Silicon 27.77%, Aluminum is 8.09% and Iron is 5% .
Which element is highest in Earth?
The most abundant element in the Earth’s crust is

, making up 46.6% of Earth’s mass.
What Colour is tin?
tin (Sn), a chemical element belonging to the carbon family, Group 14 (IVa) of the periodic table. It is a soft,
silvery white metal with a bluish tinge
, known to the ancients in bronze, an alloy with copper.
What is the most expensive thing in the universe?
An astroid named 16 Psyche, after Cupid’s wife, was found to be made almost entirely of iron and nickel. That means, in current US markets, 16 Psyche is worth somewhere around $10,000 quadrillion (the world’s economy is around $74 trillion).
Which element is hardest?
The hardest pure element is
carbon in the form of a diamond
. Diamond is not the hardest substance known to man. Some ceramics are harder, but they consist of multiple elements. Not all forms of carbon are hard.
What is the hardest thing to find on Earth?
Diamond
is the hardest naturally occurring substance found on Earth.
Is there gold in your poop?
“
The gold we found was at the level of a minimal mineral deposit
,” said co-author Dr Kathleen Smith, from the US Geological Survey (USGS). In addition to gold and silver, human waste also contains amounts of rare earth metals such as palladium and vanadium.
Is gold harmful to the human body?
Pure gold is chemically inert and passes through the human digestive system without being absorbed into the body
. Since 24-karat gold is very soft and fragile, most edible gold—whether leaf, flakes, or dust—also contains a little bit of silver, which is also inert.
