6.12: Halogens [1]
How do you study a gas that does not exist as such in nature?. Fluorine is so reactive that we cannot find it free in nature
The video below shows how violently elemental fluorine reacts with other materials.. The Group I (red) and Group II (tan) elements can easily lose electrons during a reaction
The elements of Group VIIA (new Group 17 – fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (yellow column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts
Valency of the elements in the halogen group is [2]
Valency of the elements in the halogen group is _______.. Hint:Halogens belong to group $17$ of the periodic table, consisting of highly reactive elements including fluorine, chlorine, bromine etc
In halogens, there are seven electrons in the outermost shell i.e.$ns^2 np^5$ as per the electronic configuration and they are short of one electron to achieve the nearest noble gas configuration. So, to achieve their nearest noble gas configuration they have great tendency to accept an electron, and so they are highly electronegative and thus they accept an electron exhibiting an oxidation state $\left( { – 1} \right)$ and form stable compounds
So, the correct option is $\left( A \right)$, as they are short of only one electron for completing their octet.. Halogen are highly reactive non-metallic elements in the group $17$ of the periodic table
Electronic Configuration of Group 17 Elements [3]
Inorganic chemistry is mostly liked by a lot of students. That is the popular narrative that many students believe in
If you have read some of our articles from organic chemistry, then you already know what and how we feel about it. As long as you are paying good attention to it and you are practising it enough, you will be able to score well
You must be able to pay attention to every single thing that is being told whenever any topic from Inorganic Chemistry is taught. You have studied halogens since class 10 and you have gotten a fair idea of what they are
What is the valence electron configuration for halogens? [4]
What is the valence electron configuration for halogens?. The Halogens (F, Cl, Br, I, At) are found in column 17 or the fifth column of the ‘p’ block of the periodic table
The electronic configuration of halogens in their valence shell is: [5]
The electronic configuration of halogens in their valence shell is:. Hint :In order to answer the given question, to know the electronic configuration of halogens in their valence shell, we should go through the periodic table and the configuration of the whole halogen group.
Fluorine and chlorine are gases at room temperature, while bromine is a liquid. The reactivity of halogens decreases as they progress from fluorine to astatine.
When halogens are bound to hydrogen, they all produce acids. The majority of halogens are made from minerals or salts
[Solved] The general electronic configuration ns2np5 fits which of th [6]
The general electronic configuration ns2np5 fits which of the following elements?. The elements of Group 17 (fluorine (F) – 9, chlorine (Cl) – 17, bromine (Br) – 35, iodine (I) – 53 and astatine (At) – 85) are called the halogens

Halogen | Elements, Examples, Properties, Uses, & Facts [7]
Our editors will review what you’ve submitted and determine whether to revise the article.. – organohalogen compound iodine fluorine chlorine bromine
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts)
Because of their great reactivity, the free halogen elements are not found in nature. In combined form, fluorine is the most abundant of the halogens in Earth’s crust
Valency of the elements in the Halogen Group Is______. [8]
Name or state the following with reference to the elements of the first three periods of the periodic table.. (d) Noble gas having electronic configuration 2, 8, 8.
(g) Non-metallic elements present in the period 3 of group 15 and group 16. (h) An electrovalent compound formed by an alkaline earth metal and a halogen.
(j) Alkali metal in period 3 that dissolves in water giving a strong alkali.
Electron Configurations & The Periodic Table [9]
Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements
According to the Aufbau principle, the electrons of an atom occupy quantum levels or orbitals starting from the lowest energy level, and proceeding to the highest, with each orbital holding a maximum of two paired electrons (opposite spins).. Electron shell #1 has the lowest energy and its s-orbital is the first to be filled
As we progress from lithium (atomic number=3) to neon (atomic number=10) across the second row or period of the table, all these atoms start with a filled 1s-orbital, and the 2s-orbital is occupied with an electron pair before the 2p-orbitals are filled. In the third period of the table, the atoms all have a neon-like core of 10 electrons, and shell #3 is occupied progressively with eight electrons, starting with the 3s-orbital
Valence electron [10]
In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each contributing one valence electron.
In this way, a given element’s reactivity is highly dependent upon its electronic configuration. For a main-group element, a valence electron can exist only in the outermost electron shell; for a transition metal, a valence electron can also be in an inner shell.
Atoms with one or two valence electrons more than a closed shell are highly reactive due to the relatively low energy to remove the extra valence electrons to form a positive ion. An atom with one or two electrons fewer than a closed shell is reactive due to its tendency either to gain the missing valence electrons and form a negative ion, or else to share valence electrons and form a covalent bond.
(a) The number of electrons in the valence shell of a halogen is ………. A – 1, B – 3, C – 5, D – 7. [11]
(b) Electronegativity across the period ………… [increases/decreases].. (c) Non-metallic character down the group ………… [increases/decreases].
(a) The number of electrons in the valence shell of a halogen is 7.. (c) Non-metallic character down the group decreases.
