  • With which group do halogens react most readily?
    Halogens react most readily with alkali metals (Group 1A) to form ionic salts.
  • What is the general trend for the reactivity of halogens as you move down the group?
    The reactivity of halogens decreases as you move down the group from fluorine to iodine.
  • Which halogen is the most reactive?
    Fluorine is the most reactive halogen.
  • Which element among sodium, chlorine, magnesium, and neon is a halogen?
    Chlorine is a halogen.
  • What properties do halogens have in common?
    Halogens are diatomic, highly reactive nonmetals, have a common oxidation state of -1, and display increasing intermolecular forces down the group.
  • Which statements accurately describe all halogen elements?
    All halogens are found in Group 7A, are diatomic in their elemental form, and tend to gain one electron to form a -1 anion.
  • Why do halogens tend to form anions?
    Halogens tend to form anions because they have seven valence electrons and need one more to achieve a stable octet.
  • Why are halogens destructive to ozone in the atmosphere?
    Halogens are destructive to ozone because they are highly reactive with oxygen-containing compounds, breaking down ozone molecules.
  • How does the physical state of halogens change as you move down Group 7A?
    The physical state of halogens changes from gas (fluorine and chlorine) to liquid (bromine) to solid (iodine) as you move down the group due to increasing intermolecular forces.
  • Which halogen among fluorine, chlorine, bromine, and iodine has the highest boiling point, and why?
    Iodine has the highest boiling point among the halogens fluorine, chlorine, bromine, and iodine. This is because as you move down the group, the strength of London dispersion forces increases due to larger atomic size, resulting in higher boiling points. Iodine, being the largest, is a solid at room temperature and has the strongest intermolecular forces among these halogens.
