halogens are much more reactive

∙ 12y agoHalogens 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 :)

∙ 12y agohalogens 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.

∙ 12y agoBecause 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.

∙ 11y agoThe 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.

∙ 7y agoNoble 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.

What is a Column in science?
This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
What are two symbols for halogens?
We find five halogens in periodic table. Those are non metal elements. Fluorine and chlorine gases are examples.
What is the name given to the elements in group 8?
=NOBLE GASES=
Why is bromine a gas inside a working light bulb?
Trace amounts of halogens such as iodine and bromine are used in halogen lamps (bulbs) to prevent the evaporation of ionized metals from the filaments of the bulbs. A chemical reaction with the halogens returns vaporized metal (such as tungsten) back to the filament. The result is reduced darkening of the bulb interior and a longer bulb life at hotter filament temperatures. Compounds containing bromine are mixed with non-reactive noble gases in quartz halogen bulbs.
How many groups are there in the Periodic Table?
Group 2:Alkaline Earth Metals Groups 3-12: Transitional Metals Groups 13&14: Unnamed Group 15:Pnictogens or Pnicogens) Group 16: Chalcogens Group 17: Halogens Group 18: Noble Gases *excluding hydrogen (hydrogen is in its own group) there are about 18
How do the physical and chemical properties of the halogens compare with those of the noble glasses?
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
What are two types of gases?
halogens and noble
How are halogens and noble gases alike?
they have similar properties
What is the column left to the noble gases called?
Halogens
What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
How do physical and chemical properties of the halogens compare with those of the noble gases?
Noble gases are not reactiveHalogens are very reactive.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
What is the relationship between halogen and a noble gas?
atomic number fall into groups and periods....groups two of which are halogens and noble gases... means halogens and noble gases are related to each other by groups... hope i helped...
How do the physical and chemical propertys of the halogens compare with those of the inert gases?
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
