What are charateristic of a ionic bond and a chemical bond?
Answered below for characteristics of ionic bonds. I don't understand characteristics of chemical bond since an ionic bond is a chemical bond. Perhaps you can rephrase your question. For my partial answer look on this page about half dozen questions below. Repost if this doesn't solve your problem.
chemical bonding:-ionic bond
(intermolecular force is not a bond)
in fact,all bonding have an aim.it is to make the outermost cell of the atom be full of electrons(8 electrons or 2 electrons,two electrons is only for the first cell which is tend to be an outermost cell).
-usually metal + non metal
(K+ + Cl- ==>KCl)
(Ca2+ + CO3 2- ==> CaCO3)
(Hg+ + O2-)==>Hg2O
but there are exception,
NH4+ is not a metal ion
(NH4+ + NO3- ==> NH4NO3)
Metal LOSE electrons form cation(+ve)
Cation are always metal except NH4+ and H+
other elements gain electrons to form anion(-ve).They must not be metal
eg.(K lose one electrons become K+)
(Cl atom gain one electrons become Cl- )
anion gain electrons from cation,as one positive charge(K+)and negative charge(Cl-)meet,they tend to form ionic compound.(they attach to each other becuz positive and negative attract each other)
Charge are fixed.
eg. Mg(2,8,2)Lose 2 electrons become Mg2+ (2,8).so there are no Mg+ or Mg3+...
Zn2+ + Cl- ==>?
becuz Cl- has one negative charge,it need two of Cl- to cancel out the 2+ charge of Zn
more about ionic bond:
constituent elements(cation + anion)
Types of forces(stron ionic bonds between oppositely charged ions)
hardness of solid(hard)
**Melting and boiling pt.(high,becuz strong ionic bond between anion and cation,large amount of heat energey is needed to overcome the bond in order to melt it)
(good conductors in molten state(l) or aqueous solution(aq)
its due to the mobile ion in only liquid form or in aqueous solution.
Bear in mind,in solid,ion are fixed and not mobile)
Hope my explanation can help u
