Valency example sentences

A single bond is also represented by a line between the two atoms, as shown in Figureure The atomic number of chlorine is 1 What would be its electronic configureuration and its valency? Chlorine forms a diatomic molecule, Cl Can you draw the electron dot structure for this molecule? Note that only the valence shell electrons need to be depicted.As a consequence of this, the maximum covalency of the first member of each group.One of these bonds is a double-bond, and thus the valency of carbon is satisfied.Methane has a formula CH Hydrogen, as you know, has a valency of Carbon is tetravalent because it has four valence electrons.The functional group is attached to the carbon chain through this valency by replacing one hydrogen atom or atoms.Since carbon has a valency of four, it is capable of bonding with four other atoms of carbon or atoms of some other mono-valent element.Some important functional groups are given in the Table Free valency or valencies of the group are shown by the single line.The two characteristic features seen in carbon, that is, tetravalency and catenation, put together give rise to a large number of compounds.
