Properties of Ionic & Covalent Compounds Ionic Compounds: 1.All ionic compounds have high mp/bp. OR All ionic compounds are solid in normal conditions (ntp) / their normal physical states. Note: Normal conditions (ntp): Pressure=1atm (atmospheric pressure) & Temperature=25oC 2.All ionic ...
Lab: Properties of Ionic and Covalent Compounds Introduction: Ionic compounds (or salts) are formed when metals transfer electrons to nonmetals. The loss of electrons by the metal atom transforms it into a positive ion, orcation. The gain of electrons by the nonmetal atom transforms it into a...
Covalent compounds are formed when electrons are shared between the atoms and due to this sharing of electrons, they exhibit unique physical properties as compared to ionic compounds.Answer and Explanation: Some of the main properties of covalent compounds are : 1. Covalent compounds have a very ...

e., electrically uniform—while those between unlike atoms are polar—i.e., oneatomis slightly negatively charged and the other is slightly positively charged. This partial ionic character of covalent bonds increases with the difference in the electronegativities of the two atoms.See alsoionic ...
The proportions in which atoms of elements combined to form ionic or covalent compounds (their “valences”) were thus controlled by the behaviour of their outermost electrons, which—for this reason—were called valence electrons. This theory explained the chemical bonding of the reactive elements,...
These improvements could be partly ascribed to the use of a dicarboxylic acid, which decreases the spacing between chitosan chains as a consequence of ionic crosslinking. Moreover, the addition of the strong base to the hydrogel promotes the formation of amide bonds, as suggested by FTIR ...
