An atom of a chemical element participates in a covalent bond when it shares one or more of its available valence electrons. The concept of electronegativity refers to this type of chemical bond. As the participating atom becomes more electronegative, the bonding (share...
aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds.[translate]...
- Covalent Bond: Hydrogen can also form covalent bonds, as seen in hydrogen chloride (HCl), where it shares an electron with chlorine (Cl), resulting in a covalent bond. Hint: Hydrogen can either lose an electron to form a positive ion (ionic bond) or share electrons (covalent bond). ...
How is a covalent bond formed? Covalent bonds, which hold the atoms within an individual molecule together, are formedby the sharing of electrons in the outer atomic orbitals. The distribution of shared as well as unshared electrons in outer orbitals is a major determinant of the three-dimensio...
As the positive charge on the central metal atom increase, the more readily the metal can donate its electrons to the antibonding p-orbital of carbonyl ligand. This bonding increases the strength of the metal –carbonyl bond and thus weakens the carbon-oxygen bond b...
