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.
Helium has the highest ionization energy of all the elements because it has a full outer electron shell, making it very stable and reluctant to lose an electron.
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.
Helium, fluorine, and chlorine are all elements found on the periodic table. They belong to different groups: helium is a noble gas, fluorine is a halogen, and chlorine is also a halogen. They have different properties and reactivity levels.
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.
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.

The world's atmosphere includes Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, Helium, Argon, Radon, Fluorine, Chlorine, Bromine, Iodine, Neon, and more.
False. Helium, argon, and radon are noble gases, not members of the halogen family. Halogens include elements like fluorine, chlorine, bromine, and iodine.
Any of the Halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine) or Noble Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) would be considered a nonmetal.
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.
The reactivity of an element increases towards the top and right of the periodic table (until the column of noble gases is reached). Chlorine's outer shell contains 7 electrons that make it very reactive. Helium is a noble gas and is non reactive. Elements found in the middle of the table, like nickel and iron, are reactive, but less reactive than chlorine
There are seven elements that form diatomic molecules they are: hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).
Halogens are group 17 elements (fluorine, chlorine, bromine, iodine and astatine). Noble gases are group 18 elements (helium, neon, argon, krypton, xenon and radon)
Those chemicals do not combine to make any one compound.
