The power of an element to combine with other elements is represented by an assigned number called the valence. For ions, the valence is equal to the electrical charge. For example, the valence for chlorine is 3p5, so it will easily gain one electron, and the resulting ion is Cl-. The...

A hydrogen bond occurs under specific condition, where a hydrogen atom which is already bonded to a highly electronegative atom (one of the three; oxygen, nitrogen or fluorine) experiences another force of attraction from a nearby atom that is also highly electronegative. 2. Covalent bonds ...
The sheer number of hydrogen bonds in pure water accounts for its unique properties, such as its role as a biochemical solvent, high boiling point, high dielectric constant, and high surface tension. Hydrogen Bonds in DNA Molecules DNA strands are held together into a double helical structure by...
Comparing the strength of covalent bonds, intermolecular hydrogen bonds and other intermolecular interactions for organic molecules: X-ray diffraction data and ... Gavezzotti,Angelo - 《New Journal of Chemistry》 被引量: 0发表: 2016年 Comparing the strength of covalent bonds, intermolecular hydrogen...
Hydrogen bonding is that the interaction involving a atom placed between a combine of alternative atoms having a high affinity for electrons; such a bond is weaker than an bond or bond however stronger than van der Waals forces. element bonds will exist between atoms in numerous molecul...
The total number of hydrogen bonds formed between water molecules is 4. Each water molecule can form 2 hydrogen bonds between oxygen and the two hydrogen atoms in the molecule. An additional two bonds can be formed between each hydrogen atom and nearby oxygen atoms. ...
The structures, interaction energies and vibrational spectra of a large number of molecular complexes, formed by binary combination of the covalent hydrides of some of the elements of the first two rows of the periodic table, have been determined by means of ab initio molecular orbital theory at...
The protein and MXene Ti3C2Tx were bonded by hydrogen bonds due to their abundant hydrogen bond donors and acceptors. The electrical characteristics of the composite biomaterial could be modified without changing the quantity of each component by varying the number of repeating amino acid sequence ...
