How do halogens differ from noble gases?

Answer 1

halogens are much more reactive

Answer 2

Halogens actually are not all gases (At is a solid); noble gases are all gases.

Chemically, halogens are extremely reactive, whereas noble gases don't react at all, it has full outer shell so it doesn't need to gain or lose electrons (Kr, Xe, and Rn do under high pressure and temp and only with F, Cl, or

Br.) Hope this helps :)

Answer 3

halogens consist of diatomic molecules(each molecule contains 2 atoms) while noble gases are all monoatomic gases(each molecule consists of a single atom). Halogens are non-metals with low boiling points and noble gases are all unreactive gases because they have full outer shellfs of electrons.

Answer 4

Because of the seven valence electrons in their outer shells, halogens have a very high electronegativity. They are therefore much more reactive than noble gases, which have filled outer shells.

Answer 5

The halogens form diatomic gases or solids. The noble gases are all monoatomic gases at normal temperatues and pressures. The halogens are all coloured, yellow fluorine through to deep violetbrown iodine, the noble gases are all colorless. The halogens are reactive the noble gases are not.

Answer 6

Noble gasses, having a full shell of valence electrons, are chemically stable and rarely form chemical bonds. They exist as monotonic gasses. Halogens are one electron short of a full valance shell, which makes them highly reactive. In elemental form they exist as diatomic molecules but their high reactivity means that they are usually found in compounds. They readily form negatively charged ions and tend to be strong oxidizers. Of the halogens only fluorine and chlorine are gasses at room temperature. Bromine is a liquid and iodine is a solid.

Answer 7

Halogens are very chemically reactive elements and noble gases are practically unreactive.

Answer 8

halogens are not stable while while noble gases are.
