1.How is it possible to predict if a bond is ionic or covalent?What types of atoms generally form ionic or covalent bonds?How can electronegativities be used to determine the type of bond?(8 points) 2.Draw Lewis dot structures of the diatomic molecules 02 and N2.How many valence ...
Is glucose ionic or covalent?Ionic and Covalent Bonds:In covalent bonds, atoms share electrons. Ionic bonds, on the other hand, form when one atom donates an electron to another atom. This results in two charged atoms, one negative and one positive. The positive and negative charges are ...
Expansion of the ideal covalent and ionic models leads chemists to the concepts of electronegativity and polarizability, and thus to the classification of polar and non-polar bonds. In addition, the intermolecular interactions are normally viewed as physical phenomena without direct correlation to the ...
