Which nonmetal is the most reactive?

Which nonmetal is the most reactive?

element fluorine
The element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.

Which family of nonmetals are most reactive?

halogens
The halogens are the most reactive elements; especially fluorine.

Where are most reactive nonmetals on periodic table?

The most reactive nonmetals are the halogens (of group 17), which are located on the far right-hand side of the periodic table, just before the noble…

Are all nonmetals reactive?

Nonmetals are elements that generally cannot conduct electricity. Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level. Reactive nonmetals tend to gain electrons.

Which nonmetals are the most reactive and why?

Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.

Which of the following nonmetals is the least reactive?

helium
The least reactive non-metal is helium. Helium is a noble gas at the top of the noble gas family, which is group 18.

Are nonmetals reactive or nonreactive?

Properties of nonmetals include a relatively low boiling point, so many nonmetals are gases. Nonmetals are also poor conductors of heat, and solid nonmetals are dull and brittle. Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level.

Which group has most active nonmetals?

halogen family
The most active group of nonmetals belong to the halogen family. These include fluorine, chlorine, bromine, iodine and . In the periodic table, they appear to the left of the noble gases on the right side of the table. They are so reactive that they are never found in nature by themselves.

Which group is the most reactive?

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Are nonmetals reactive?

Which nonmetals are non reactive?

Helium
Helium is the least reactive non metal. Helium is a chemical element with the symbol He and atomic number 2.

Where are most nonmetals located?

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.

Which group contains the most reactive non metals?

Most reactive non-metal is flourine and the most reactive metal is francium. It is so because of the increasing metallic nature down a group and decreasing metallic nature across a period. The nuclear charge is also a factor.

What are the most reactive metals and non-metals?

The most reactive metal is: (a) Iron (b) Gold (c) Zinc (d) Potassium. The liquid metal at room temperature (a) Mercury (b) Bromine (c) Sodium (d) Gold. Non-metals are: (a) generally liquids (b) generally gases (c) generally solids and gases (d) generally gases and liquids.

What family are very reactive non metals?

Halogen Family of Elements Group 17 or VIIA Halogens 7 valence electrons Reactive nonmetals Melting points and boiling points increase with increasing atomic number High electron affinities Change state as it moves down the family, with fluorine and chlorine existing as gases at room temperature while bromine is a liquid and iodine is a solid

What is more reactive metals or non metals?

The elements of lower valency are more reactive than those which have more valency. Metals with a big atomic size and non- metals with a small atomic size are more active than others. In a group, the reactivity of metals increases from top to bottom and that of non- metals decreases from top to bottom.
