Basically, bonding orbitals are the electron hangout spots that hold atoms together in a bond. sigma bond is a type of bond formed when two atoms overlap their orbitals end-to-end. It's the strongest bond and is found in single bonds.Think of it like two people shaking hands—the bond ...

What is the difference between an ionic and a covalent bond? Describe how each of these bonds is formed. How does non covalent bonding hold a clathrate together? Why are electrons shared in covalent compounds? What is a chemical bond? How does ionic bond differs from covalent bond?
calculating enthalpies in this manner, it is important that we consider the bonding in all reactants and products. Because D values are typically averages for one type of bond in many different molecules, this calculation provides a rough estimate, not an exact value, for the enthalpy of ...

Why does metallic bonding only occur between metals? Why is the electronegativity of an element important? Why do nonmetals gain electrons? What is the difference between covalent and ionic bonds? Why do ionic compounds conduct electricity?
