What is ionic bonding structure?

Ionic bond is when a non-metal takes the metals valance electrons so both atoms can be balanced. Take NaCl for example. Na has one valance electron and Cl only needs one to get eight. So Cl takes Na's one valance electron...:Cl: Na. See the empty spot for Cl, that where Na's valance electron will go.'

Is chlorine an electron doner or an acceptor?

Chlorine has 7 valance electrons so the easiest way for it to fill it's valance shell and have an octet is to be an electron acceptor; an anion.

How many valence electrons does chlorine have?

Chlorine has seven valence electrons. The electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p5. These seven valance electrons do NOT readily react, because they are 'tightly' held to the nucleus. However, chlorine has strong electron affinity; Electronegativity; this means it will attract one electron into its valance shell , to complete the octet of eight electrons in the valance shell. When this 'extra' electron combines into to valance shell , the electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6. , and the chlorine atom is now a 'CHLORIDE ANION' of charge '-1' , (symbolised by Cl^(-)).
