Respuesta :
An ionic bond is a bond which occurs when there is a difference in the electronegativity of the atoms. One atom which has a stronger electronegativity tends to steal the electron of the other less electronegative atom hence making it more negative (anion), while the other becomes a cation. So answer is:
b. a cation and an anion
1.) 2
2.) k+
3.) It gains electrons
4.) The attraction of metal ions to mobile electrons
5.) A cation ans an anion
6.) body-centered cubic
