How is terylene formed? Sodium is much more apt to exist as a positive ion than is chlorine. Why does this occur? How is phosphorous acid manufactured? Why does sodium chloride normally exist as a crystal rather than as a molecule composed of one cation and one anion?
as it is a matter of little importance to us, it doesn’t make much sense to argue out which is wrong or right or which is better or worse it makes no sense to compel children to obey their parents; instead, we should try to tell them what is right and what is wrong. EX. 7. ...

When there are positive and negative charges on lot of atoms or higher charges (like +2, +3, -2, -3) on atoms in an ion or molecule, that structure is not stable. Therefore, We should try to reduce charges on atoms if it is a possible. In step 3 we can see that the externa...
Why can transition metals form bonds with more than one ion? How can one tell what bonds have been broken and what bonds have been formed from a chemical reaction? In ionic bonding, why are atoms losing an electron forms positive ions but not negative ions, and similarly atoms gains an el...
How is the molecular ion of α‐tocopherol formed under fast atom bombardment conditions?The mechanism for the formation of the M +· ion of α‐tocopherol, a viscous oily material, under fast atom bombardment (FAB) conditions without a liquid matrix was investigated by using positive‐ and/or...
An ion is a charged atom. If an atom gains an electron, the negative charge outweighs the positive charge, and the whole atom gains a negative charge. These ions are called anions. If the atom loses an electron, then there is more positive charge than negative charge, and the atom as ...
The positive currents in the anodic potential regime reveal the anodic oxidation and dissolution of the metal, and the steep increase is associated with significant metal dissolution and release rates. The metal species are dissolved at the anodic potential of −0.6 V, and directly past that...
When a metal atom loses an electron, a positive ion or cation is formed by donating the same to a non-metal atom. The non-metal atom receiving the electron forms a negative ion, an anion. Answer and Explanation: A hydrated ion is an ion that exists as...
2j). The positive sign of the cumulative twist difference indicates that the filament is slightly over-twisted compared to the straight, symmetric case. The small torsional elastic strain energy (Es « kBT, calculated using a filament torsional persistence length LT value of 10 µm15) ...
