Why is hydrogen a special element?
Hydrogen is special among the elements for the reason it can easily form compounds in either the +1 or -1 oxidation states, where it can act essentially like a metal or a non-metal, depending on the circumstances.
This fact is what allows hydrogen to be present in so many different compounds..
Which element is most unique?
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)
Who invented oxygen?

What are 3 interesting facts about hydrogen?
5 interesting facts about Hydrogen:Element number one wasn’t the first element discovered.Hydrogen is the only “neutron-less” element in the universe.Hydrogen’s presence in water is not the only reason it is essential for life.Hydrogen already powers everything you use.More items…•Jun 14, 2016
What is the rarest element in the universe?
AstatineAstatine is the rarest naturally occurring element.
Is hydrogen harmful to humans?
Yes, hydrogen is harmful to humans. Inhalation of high concentration of hydrogen can cause asphyxiation. … Asphyxiation means being deprived of oxygen, which can cause suffocation, unconsciousness and death.
What is unique about hydrogen?
Hydrogen is a colorless gas that is so much lighter than air that it can actually escape the gravitational pull of the earth and shoot off into space. Hydrogen is also the first element on the periodic table and has only on proton and one electron. Hydrogen does not have any neutrons.
What are 5 interesting facts about hydrogen?
Here are five things to know about hydrogen and fuel cells.Hydrogen is the most abundant element on earth. … Fuel cells can be used to power several applications. … Fuel cells are a clean way to produce power. … Fuel cell cars are very similar to traditional gasoline powered cars.Oct 4, 2017
How dangerous is hydrogen?
When liquid hydrogen is stored in tanks, it’s relatively safe, but if it escapes there are associated hazards. Topping the list of concerns is hydrogen burns. In the presence of an oxidizer — oxygen is a good one — hydrogen can catch fire, sometimes explosively, and it burns more easily than gasoline does.
Which two groups can hydrogen act like?
Hydrogen as a halogen? Hydrogen, like the halogens, has one electron short of a complete outer shell and can form H- ions like Cl- and therefore forms ionic compounds with reactive metals – NaH similar in structure to NaCl. Hydrogen also exists as a diatomic gas like fluorine and chlorine.
Where do we find hydrogen?
Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
Why is hydrogen the most important element?
Hydrogen plays a vital role in fusion reactions that power stars like our sun. These reactions not only produce heavier elements but also release very large amounts of energy. The vast amounts of energy emitted by the sun come from nuclear reactions that fuse hydrogen atoms into helium atoms.
What is the color for hydrogen?
colorlessAlthough hydrogen is actually a colorless gas, it is commonly referred to by a color to denote how clean it is: black, gray and brown being least clean, a cleaner blue and a true zero-emission green hydrogen. Roughly 95% of hydrogen is fossil-based.
Why is hydrogen important to life?
The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons etc.
What things have hydrogen in them?
Hydrogen combines with other elements to form numerous compounds. Some of the common ones are: water (H2O), ammonia (NH3), methane (CH4), table sugar (C12H22O11), hydrogen peroxide (H2O2) and hydrochloric acid (HCl). Hydrogen has three common isotopes.
