fluorine bromine chlorine
The halogens, which are the most reactive negatively charged particles (fluorine, chlorine, bromine, iodine) The better reactions with potassium are the ones close to the other side of the periodic table (excluding noble gases like helium, neon, argon, xenon and krypton).
Bromine and Chlorine are gases.Sodium and sulphar are solid.Mercury is a liquid.All are reactive.Helium is the only inactive gas.
Those are all gases at room temperature.
Anything to the right of the step-like line.
fluorine bromine chlorine
The most reactive is fluorine.
The halogens, which are the most reactive negatively charged particles (fluorine, chlorine, bromine, iodine) The better reactions with potassium are the ones close to the other side of the periodic table (excluding noble gases like helium, neon, argon, xenon and krypton).
The world's atmosphere includes Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, Helium, Argon, Radon, Fluorine, Chlorine, Bromine, Iodine, Neon, and more.
Any of the Halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine) or Noble Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) would be considered a nonmetal.
Bromine and Chlorine are gases.Sodium and sulphar are solid.Mercury is a liquid.All are reactive.Helium is the only inactive gas.
hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, astatine, radon
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.
Helium is the least reactive element, to the point of being unreactive.
Those are all gases at room temperature.
Hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, bromine, krypton, xenon and radon are all gases at 100 deg C. Only Bromine will condense if cooled to room temperature.
