What is the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
What are the 2 groups of non-metal?
There are 3 groups of non-metals in which they are : Halogens, Noble Gases and Other nonmetals
What are the nonmetals in Group 7A called?
The nonmetals in Group 7A are called halogens. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive elements that tend to form salts when they react with metals.
Is a halogen a nonmetal?
Yes, halogens are nonmetals. They are located in group 17 of the periodic table and are known for their high reactivity and tendency to form salts with metals. Examples of halogens include fluorine, chlorine, bromine, and iodine.
What is the most active group of nonmetals noble gases alkali metals halogens alkaline earth?
The most active metals are alkali metals.The most active nonmetals are halogens.
Classes of elements?
Elements are classified into metals, metalloids, and nonmetals based on their physical and chemical properties. Metals are typically shiny, conduct heat and electricity well, and are malleable. Metalloids have properties that are intermediate between metals and nonmetals. Nonmetals are usually dull in appearance and poor conductors of heat and electricity.
The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
What are the non metals in halogens?
All halogens are nonmetals, with the possible exception of astatine, which has no stable isotopes (its MOST stable isotope has a half-life of about 8 hours) and has never been observed in bulk. Astatine may be a semiconductor or even metallic in character; we just don't really know.
Which property is common to all halogens?
Halogens are all non-metals, they are all very reactive, and they are all colorful.
Do halogens have high density?
No, halogens do not have high density. Halogens are all nonmetals and are typically lighter than metals, so they have lower densities.
Are the halogens most reactive nonmetals or the least reactive nonmetals?
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.
Are halogens good conductors of electricity?
Bromine is a liquid at room temperature, and it is located in group 7 of the periodic table, i.e., it is a halogen. It is a non-metal and thus is a poor conductor of both electricity and heat.
