The most reactive nonmetal is fluorine, F. The trend in reactivity in the nonmetals is the opposite of the trend in the metals. In the nonmetals, reactivity increases as you move up a group, and to the left.

What is the most reactive nonmetal and why?

Fluorine is the most reactive nonmetal because it is the most electronegative nonmetal in the periodic table. Fluorine is the only element that reacts with Xenon of VIII A group, due to its high electronegativity value.

What are the 2 most reactive non metals?

> Chlorine is the most receptive metal in the halogen family for example Chlorine, Bromine, Iodine, and Fluorine. > Thus, from the given options; Fluorine is the most responsive non-metal since it is the most electronegative of the entirety of the non-metal components of the periodic table.

Is Group 18 the most reactive nonmetals?

Group 18: Noble Gases Group 18 elements are nonmetals called noble gases (see Figure below). They are all colorless, odorless gases. Their outer energy level is also full, so they are the least reactive elements. In nature, they seldom combine with other substances.

Where are the most reactive nonmetals elements found on the periodic table?

The most reactive nonmetal elements on the periodic table are found in group 17, and they are known as the halogens.

Are nonmetals the most reactive?

Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal.

Where are the most reactive nonmetals found on the periodic table quizlet?

Halogens (group 17) are the most reactive nonmetallic elements.

Which of the following nonmetals is most active?

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.

Which non metal is the most reactive of group 17?

Fluorine is the most reactive non- metal of group 17 in the periodic table.

Which is the highest reactive element?

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.

Which group is the most inert nonmetals?

Noble gases are a group of nonmetals in group 18 that are often described as chemically inert – they are colorless, odorless and highly unreactive. This group includes helium, neon, argon, krypton, xenon, radon, and the synthetic element oganesson.

Why are nonmetals reactive?

Reactivity of Nonmetals The answer is their number of valence electrons. These are the electrons in the outer energy level of an atom that are involved in interactions with other atoms. As a result, fluorine is highly reactive. In fact, reactions with fluorine are often explosive.

Which one of the following are very reactive nonmetals?

The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive

Where are the most reactive nonmetals on the periodic table at the top of group 17?

Across a period from left to right, the elements become less metallic and more nonmetallic in their properties. The most reactive metals are on the left side of the table. The most reactive nonmetals are on the right side in group 17.

Which of the following nonmetals is the least reactive?

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

Which nonmetals is likely to be the least reactive?

Explanation: fluorine and chlorine are in the same group and they are the least of the 4 you gave.
