Can someone please help me with this?

Ionic bond is a type of bond which is formed between metals and non-metals. The group which provide the Metal are IA and IIA i.e. S block elements. The group which mostly provide non-metal is VII A i.e. halogens. The Metals give up their ONLY Valance shell electron which is accepted by the Non-metal. This results in formation of ions, The Metals gets the positive charge thus called cation and The non-metal gets a negative charge thus called anion. These Positive and Negative ion attract each other resulting in the formation of IONIC BOND.

The Ionic bond is formed between The metal and non metal because, the metals have low ionization energy due to which the valence shell is ejected out easily, and The Non-Metals have high electron affinity which means that  they attract an electron with greater force because they need one electron to complete their octet.

Question has given two atoms Potassium and chlorine. Potassium(Group 1) is metal, Chlorine(Group 7) is non metal. As you can se that there is only one electron in the outer shell of Potassium "K" and Chlorine need only one electron to complete its outer shell so Potassium will give its electron to Chlorine. Due to this reason K will become positive and Cl will become negative and they will both attract eachother forming ionic bond.

So the answer is Option C: Electron will be transferred from the potassium to the chlorine atom.

your answers are a,b,,e and f

i hope this
