because helium has a full outermost shell, which has a capacity of 2 electrons whereas fluorine has 2 shells, the outermost having a capacity of 8 electrons and has, by nature, only 7 electrons.
elements in general, atleast up to the 20th element, the first shell has a capacity of 2 electrons, the 2nd shell has a capacity of 8 electrons, the third has a capacity of 8 electrons.
also there are elements that are not reactive and are known as the noble gasses. these are helium, neon, argon, xenon, etc and are known as the noble gasses. these elements which happen to be present in the form of gasses has full outermost shells, that is if the outermost shell has a capacity of 2electrons then it actually has, by nature, 2 electrons in it, and if it has a capacity of 8 electrons, then it has 8 electrons in it and so on. hence non reactive because there is no 'free' electrons or space to hold 'extra' electrons.
What else can I help you with?
What is the most reactive chlorine bromine fluorine and helium?
Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.
Does helium and fluorine have a similar reaction?
Helium is inert and does not readily react with other elements, including fluorine. Fluorine is a highly reactive element and will readily react with many other elements, but not with helium due to its stable electron configuration.
What does fluorine and helium make together?
Fluorine is a highly reactive element, while helium is inert. When combined, fluorine and helium do not form a stable compound or molecule. Helium is typically used to inertly fill containers to prevent reaction with other substances.
Is helium more reactive than fluorine?
No, fluorine is more reactive than helium. Helium is a noble gas and is considered to be inert, meaning it does not readily form compounds with other elements. Fluorine, on the other hand, is a highly reactive nonmetal that readily reacts with many other elements.
Which element forms compounds with all other elements except helium neon and argon?
The element that forms compounds with all other elements except helium, neon, and argon is fluorine. Fluorine is the most reactive nonmetal and readily forms compounds with almost all other elements due to its strong electron-attracting abilities.
Which element is most reactive lithium carbon fluorine or helium?
The most reactive is fluorine.
What is the most reactive chlorine bromine fluorine and helium?
Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.
Does helium and fluorine have a similar reaction?
Helium is inert and does not readily react with other elements, including fluorine. Fluorine is a highly reactive element and will readily react with many other elements, but not with helium due to its stable electron configuration.
How is fluorine different from helium?
Fluorine is a chemical element with atomic number 9, while helium is element number 2. Fluorine is a highly reactive nonmetal, while helium is a noble gas known for its inertness. Fluorine is commonly found in compounds like fluorides, while helium is often used in balloons and cryogenics due to its low boiling point.
What does fluorine and helium make together?
Fluorine is a highly reactive element, while helium is inert. When combined, fluorine and helium do not form a stable compound or molecule. Helium is typically used to inertly fill containers to prevent reaction with other substances.
Is helium more reactive than fluorine?
No, fluorine is more reactive than helium. Helium is a noble gas and is considered to be inert, meaning it does not readily form compounds with other elements. Fluorine, on the other hand, is a highly reactive nonmetal that readily reacts with many other elements.
Which is more unreactive helium or krypton?
Helium is more unreactive than krypton. Helium is a noble gas located in the first group of the periodic table, making it the least reactive element. Krypton, also a noble gas, is located in the same group but is slightly more reactive than helium.
Which element forms compounds with all other elements except helium neon and argon?
The element that forms compounds with all other elements except helium, neon, and argon is fluorine. Fluorine is the most reactive nonmetal and readily forms compounds with almost all other elements due to its strong electron-attracting abilities.
Where is fluorine in in the periodic table?
Fluorine is element number nine on the periodic table. Look for it to the bottom left of Helium (the top right one). Second row, two from the left.
Which is the most reactive gas on the periodic table?
Fluorine is the most reactive gas on the periodic table. It readily reacts with almost all other elements, including noble gases like helium.
What is the least reactive element?
The noble gases: Helium, neon, etc.
Which halogen is most likely to react?
Fluorine is the most reactive halogen because it has the highest electronegativity among the halogens and smallest atomic size, making it highly reactive and capable of forming strong chemical bonds with other elements.
