The halogen that exists as yellow-green gas
WebFluorine 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 ... WebThese reactive elements have characteristic properties, e.g., at room temperature they exist as gases (fluorine and chlorine), a liquid (bromine), and solids (iodine and astatine) with colors ranging from light and medium yellow-greens for fluorine and chlorine through deep red for bromine to almost black with a metallic lusterforiodine ...

Web21 Feb 2024 · So, for example, strontium (atomic number 38) produces a reddish color, while sodium (atomic number 11) produces a yellowish color. The sodium ion has a stronger affinity for the electron, so more energy is required to move the electron. When the electron does move, it reaches a higher state of excitement.
WebFluorine gas is deadly. Breathing air with only a small concentration of 0.1% fluorine can cause death. Small amounts of fluoride are used in water and toothpaste to help prevent tooth decay.
