Polar bondsare the dividing line between pure covalent bonding and pureionic bonding. Pure covalent bonds (nonpolar covalent bonds) share electron pairs equally between atoms. Technically, nonpolar bonding only occurs when the atoms are identical to each other (e.g., H2gas), but chemists consider...
Different flow regimes may be observed in porous media when viscoelastic polymers are involved (Fig. 5). During Regime 1, which occurs at low shear rates, the entropic forces are greater than the fluid flow-induced hydrodynamic drag forces. As a result, the polymers are maintained in the form...

not connecting hydrogen atoms and having at least one end attached to a ring. This cutting process helps divide the ligand into fragments. The FSMILES construction process occurs in two steps (Fig.1b). First, the ligand is divided into fragments according to the cutting rule. Second, ring ...
There are two main types of strong bonds between atoms, ionic bonds and covalent bonds. Ionic bonds occur when one atom donates electrons to another atom, whereas covalent bonds occur when two atoms share electrons.Answer and Explanation: A polar covalent bond is different from a nonpolar ...
Polar Covalent Bonds: For a bond to be polar covalent the electronegativity difference between the atoms forming the bond should be greater than zero but less than 2. If the electronegativity difference is 0, it is considered to be polar covalent. ...
