But I don't know how to find the covalency and oxidation state of an element in a compound. The covalency is determined by the number of electrons shared while forming a chemical compound. 9 years ago Answers : (3) SAGAR SINGH - IIT DELHI 879 Points Dear student, Valency is the combining capacity of an atom. Group 13 (3A) can form 3 covalent compounds (sharing 3 electrons) Group 14 (4A) can share 4 electrons Group 15 (5A) can share 3 electrons Group 16 (6A) - 2 electrons Group 17 (7A) - halogens share 1 electron, but they generally form ionic compounds. First, to determine the oxidation state of each atom, there are a series of rules that are followed. Share with your friends. Please send him an email using the address above; Click on Covalence to select it. Ex: Magnesium – one magnesium atom loses 2 electrons to achieve the inert gas electron configuration, therefore, the valency of magnesium is 2(or +2). What is Covalency How to find the covalency of any element - Chemistry - Classification of Elements and Periodicity in Properties Atoms of different chemical elements are bonded with each other forming different chemical compounds. The inner orbital of electrons has 2 electrons, so the next orbital has 4 (6 – 2 = 4). Dear student, Covalency is the property by which a bond is formed due the sharing of electrons between two atoms. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. A molecule or compound is made when two or more atoms form a chemical bond, linking them together.The two types of bonds are ionic bonds and covalent bonds. This chemistry video tutorial provides a basic introduction into ionic and covalent bonding. Ask your question. MEDIUM. How do you determine if a molecule is polar covalent, pure covalent or ionic?
