Where is fluorine found in earth? Fluorine. Fluorine is an univalent poisonous gaseous halogen, it is pale yellow-green and it is the most chemically reactive and electronegative of all the elements.Fluorine readily forms compounds with most other elements, even with the noble gases krypton, xenon and radon.It is so reactive that glass, metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas.luorine readily forms compounds with most other elements, even with the noble gases krypton, xenon and radon.

- Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 7000100800000000000♠1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

- Helium, which is the second most abundant element in the universe (behind hydrogen) is about a quarter of all matter. It is a gas here on earth, and can only be liquefied if it is cooled to near absolute zero. It will not solidify, by the way. Outside earth, it is mostly found in stars where it is a plasma.

It's Elemental Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is the raw fuel that most stars 'burn' to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth. The sun's supply of hydrogen is expected to last another 5 billion years. Hydrogen is a commercially important element.

What Is The Universe's Third Most Common Element? The most important thing is to stick around, because the Universe is still changing! Oxygen is the third most abundant element in the Universe today, and in the very, very far future, may even have the opportunity to rise further as hydrogen (and then possibly helium) falls from its perch.

Which element is the most massive of all elements? There are a couple of ways to answer this. 1  The element with the most collective mass in the universe is: Hydrogen (75%) 2  The element with the most collective mass on earth is Oxygen (about 46%) 3  The most massive atom that is stable is lead. 4  The most massive naturally occurring element that we know of is Uranium with an AMU of 238. There might be some wiggle room here. Some think there might be one of two that are bigger. But anything above Uranium was artificially made or lasts only a very brief period of time.

Hydrogen - H Properties: Common hydrogen has a molecular weight of 2,01594 g. As a gas it has a density of 0.071 g/l at 0ºC and 1 atm. Its relative density, compared with that of the air, is 0.0695. Hydrogen is the most flammable of all the known substances. Hydrogen is slightly more soluble in organic solvents than in water. Many metals absorb hydrogen.
