Why is group 17 the most reactive?

Why is group 17 the most reactive?

Halogens are nonmetals in group 17 (or VII) of the periodic table. Due to their high effective nuclear charge, halogens are highly electronegative. Therefore, they are highly reactive and can gain an electron through reaction with other elements.

What are the semi metals in periodic table?

Key Takeaways: Semimetals or Metalloids Usually, the semimetals or metalloids are listed as boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. Some scientists also consider tennessine and oganesson to be metalloids. Metalloids are used to make semiconductors, ceramics, polymers, and batteries.

Which is the most reactive?

Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.

Which is the most reactive group for the nonmetals?

Halogens
Halogens are the most reactive nonmetals on the periodic table. The halogens are so reactive due to their electronic configuration.

Why is Group 18 not reactive?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Which of the following element is most reactive?

Out of these four elements, fluorine is the most reactive element. Because fluorine is one of the halogens in the periodic table. Fluorine reactivity is due to the electron affinity.

Which element below is the most reactive?

D. The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.

What group of elements are very reactive metals?

Group I consist of alkali metals and these are very reactive. They rapidly react with oxygen so they should be stored out of contact with oxygen to prevent the oxidation process. By moving down the group reactivity is increased. The less reactive metals such as sodium potassium and lithium are stored in the oil to prevent the reaction of oxidation.

Which metal is the least reactive?

Elements with the Lowest Reactivity. The least reactive element is helium, which forms no compounds. The least reactive metal is platinum. Platinum cannot be oxidized in air, even at high temperatures. It is unaffected by common acids, although it can be dissolved in aqua regia (a mixture of nitric acid and hydrochloric acid in the ratio 1:3)…

Which family has the most reactive metals?

The lithium family,and the beryllium family are the most reactive metals.

Which group of nonmetals is the least reactive?

Group VIII-A elements have fully filled orbitals and hence are most stable amongst all the elements in the periodic table. They are considered as least reactive elements and as they are categorized as non-metals. So, they are the least reactive non-metals.
