10 Most Useful Chemical ElementsKrypton.
Krypton (Kr) isn’t just the element that makes Superman weak.
The element curium (Cm) is created by adding many helium ions to plutonium.
Lutetium (Lu) was discovered by Georges Urbain in 1907.
Zirconium (Zr) …
Does the human body need gold?
While the role of gold in the physiological processes of the human body was unknown for many years, it has recently been determined that gold plays a role in both the health and maintenance of the joints, as well as being a key element in the transmittal of electrical signals throughout the body.
What is the hardest thing to find on Earth?
AstatineEspecially Astatine (At). That’s pretty much the hardest thing to find anywhere. The NPR says that Astatine is so rare that it’s never even been seen directly because if you managed to actually get enough of it together, it would vaporize itself with its own radioactive heat.
Is there gold in the human body?
Average human body has 0.2 milligrams of Gold. One of the lesser know elements is actually Gold. An average person’s body weighing 70 kilograms would contain a total mass of 0.2 milligrams of gold.
What is the lightest element on earth?
HydrogenHydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas. The properties of hydrogen are summarized in Table 11.1.
What is the smallest element in the universe?
HydrogenThey are the simplest and smallest Elements – Hydrogen and Helium. A Hydrogen atom contains one Proton and zero Neutrons. When two of these join together, one of them turns into a Neutron and makes a different kind of Hydrogen (called 2H, because it has 2 particles in the atom).
What element makes up 80 percent of the air?
NitrogenNitrogen comprises the greatest part of the atmosphere, at almost 80 percent by volume. Nitrogen is a colorless, odorless, tasteless gas that reacts very little with other substances. The atmosphere also contains oxygen, at about 20 percent.
What elements are most common in the universe?
Together, helium and hydrogen make up 99.9 percent of known matter in the universe, according to Encyclopedia.com. Even so, there is still about 10 times more hydrogen than helium in the universe, Nyman said. Oxygen, the third most common element, is about 1,000 times less abundant than hydrogen, she added.
What are the 6 most common elements in the human body?
It is thus no wonder that 99% of the atoms in the human body come from six elements: Hydrogen (62.9%), oxygen (almost 24%), carbon (nearly 12%), nitrogen (nearly 0.6%), calcium (0.24%) and phosphorus (0.14%). Calcium is on the list as it is essential for our skeleton, which contains 99% of the calcium in our body.
What is the rarest element in the universe?
element astatineBut the rarest element? The radioactive element astatine is so rare that its inclusion in the Periodic Table of the Elements was made at first in theoretical character. Currently there are a total of 31 grams of the material on earth.
What is the rarest thing in earth?

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 element makes up most of 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 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%.
Is silicon a metal?
Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two. The category of metalloid is something of a gray area, with no firm definition of what fits the bill, but metalloids generally have properties of both metals and non-metals.
