Introduction ;
The introduction should set the stage for the rest of the essay by introducing the topic and providing some context. It should also include a thesis statement, which is a clear statement of the main point of the essay.
What are Halogens?
The halogens are a group of elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. These elements are all highly reactive and share some common physical and chemical properties. They are all colorless, corrosive, and poisonous.
Halogen Electron Configuration
The halogen electron configuration is a pattern of electron orbitals that is shared by all of the elements in the halogen group on the periodic table. In this configuration, the outermost electron shell is filled with seven electrons, and the next two shells are each filled with two electrons. This pattern results in a strong and stable electron configuration that allows halogens to form strong chemical bonds with other elements.
Electronic Configurations
Electronic configurations are the specific arrangements of electrons in an atom. The configurations are determined by the number of protons in the nucleus and the number of electrons in the outer shell. The configurations can be represented by electron configurations blocks.
The blocks are: s, p, d, and f. The s block consists of the first two electrons in an atom. The p block consists of the next six electrons in an atom. The d block consists of the next 10 electrons in an atom. The f block consists of the next 14 electrons in an atom. The configurations can also be represented by using numbers. The number represents the energy level of the electron. The higher the number, the higher the energy level.
Using these rules the electronic configuration of group 17 elements is ns2 np5, where n is the quantum number of the respective elements.
Let us See the Electronic of Each Element of Halogens Separately
The electronic configuration of chlorine is 1s2 2s2 2p6 3s2 3p5.
The electronic configuration of fluorine is 1s2 2s2 2p6 3s2 3p6.
The electronic configuration of bromine is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5.
The electronic configuration of iodine is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 5p5.
