Astatine is the rarest naturally occurring element.
What is the rarest man made element?
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.
What is the strangest element?
OK, let’s talk about something with pretty much no practical relevance whatsoever: the element copernicium. That’s #112, just below mercury in the periodic table, and its longest-lived isotope has a half-life of 29 seconds.
What is the least common element in the universe?
The chemical composition of the earth is quite a bit different from that of the universe. The most abundant element in the earth’s crust is oxygen, making up 46.6% of the earth’s mass. Thulium is the least abundant element.
What element makes up about 90% of the known universe?
Hydrogen is the lightest gas and element and is the most abundant in the universe. It is estimated that 90% of the visible universe is composed of hydrogen.
What is the most useless metal?
Within the standard 92 elements found in nature, most have at least some practical use, the most useless probably being Thulium, which is usually the butt of jokes on the subject, but still has some actual applications (http://en.wikipedia.org/wiki/Thulium#Applications).
What is the oldest element on Earth?
The 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.
What is the most powerful element?
Fire — The most powerful element. Nothing can exist before the most brilliant flames.
What element is the strongest?
The Top 10 Strongest Metals
| Rank | Type of Metal | Atomic Weight |
|---|---|---|
| #1 | Tungsten | 183.84 u |
| #2 | Steel | n/a |
| #3 | Chromium | 51.96 u |

What is the most expensive element in the world?
As 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 the hardest thing in the universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
What element makes up about 20% of the universe?
Answer. Helium is the second-most abundant element in the universe, after hydrogen, and accounts for about 25 percent of the atoms in the universe.
Why is lithium so rare?
Observed abundance of lithium
Hydrogen and helium are most common, residuals within the paradigm of the Big Bang. Li, Be and B are rare because they are poorly synthesized in the Big Bang and also in stars; the main source of these elements is cosmic ray spallation.
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.
What is the 2nd most abundant element in the universe?
In stars, hydrogen atoms fuse to create helium — the second most common element in the universe, according to Encyclopedia.com. Helium has two protons, two neutrons and two electrons. Together, helium and hydrogen make up 99.9 percent of known matter in the universe, according to Encyclopedia.com.
What is the most common element found 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.
