Ionic bonds form between a metal and a ____-____. The metal atom gives ____ to the non-metal ____ and they change into ____. The metal atom loses electrons and becomes a ____ ion. The non-metal atom gains electrons and becomes a ____ ion. The positive and negative ions then ____ together in a repeating 3D pattern called a ____ ____ lattice. The positive and negative ____ in a ____ ionic structure are held together by very ____ forces called ____ forces (or ____ bonds). These strong bonds exist throughout the whole giant structure and need a lot of ____ to break. The bonds need to be broken for the ionic substance to ____, so ionic substances have very ____ melting points. Ionic substances are always ____ at room temperature. Things can only ____ electricity if charged particles such as ____ or electrons can move through them. An ionic solid ____ conduct electricity because the ions can only ____ but cannot move ____ and carry the ____. When an ionic substance is melted or ____ the ions are ____ to move around and carry the charge so it ____ conduct electricity. Giant ionic structures always have ____ ions next to negative ions which strongly ____ together. If the structure is hit hard, a ____ of ions can move along one place so that the positive ____ are next to other positive ions and the ____ ions are next to other negative ions. If this happens the ions will ____ apart and the structure will ____. This is why all ionic substances are ____.
