Steps for forming ionic bonds:
1. Electron transfer: One or more electrons are transferred from one atom to the other. This step creates two oppositely charged ions.
2. Lattice formation: The positively charged ions and negatively charged ions arrange themselves in a regular lattice structure in a stable arrangement.
3. Electrostatic attraction: The positive and negative ions attract each other due to their opposite charges. This attraction results in the formation of an ionic bond between them.
For example:
- In sodium chloride (NaCl), the sodium atom loses an electron to the chlorine atom, forming a positively charged sodium ion (Na+) and a negatively charged chloride ion (Cl-). These ions are held together by the electrostatic attraction between their opposite charges.
Ionic bonds are strong because of the strong electrostatic forces between the oppositely charged ions. They typically occur between a metal atom, that easily loses electrons to be positively charged, and a non-metal atom that readily accepts them to become negatively charged.
