Student Exploration: Ionic Bonds

Ionic bonds are bonds formed between a cation and anion.

Explanation:

Ion : An ion is a charged particle which is formed due to the gain or loss of one or more electrons by an atom.

Electropositive element : A metallic element whose one readily loses electron(s) to form a positively charged ion, is an electropositive element.

Electronegative element : A non metallic element whose one atom readily gains electron(s) to form a negatively charged ion, is an electronegative element.

An ionic bond can also be defined as the bond formed by the transfer of electrons from a metallic element/electopositive element to a non metallic element/electonegative element

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
