An ionic bond at A Level chemistry is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions. This usually occurs between metal atoms, which lose electrons to become positively charged cations, and non-metal atoms, which gain those electrons to become negatively charged anions. Ionic bonding is fundamental in the structure of many compounds, leading to the formation of ionic compounds with distinct properties such as high melting and boiling points, and the ability to conduct electricity when molten or dissolved in water.
FAQs & Answers
- What types of atoms form ionic bonds? Ionic bonds typically form between metal atoms, which lose electrons to become cations, and non-metal atoms, which gain electrons to become anions.
- Why do ionic compounds have high melting and boiling points? Ionic compounds have high melting and boiling points due to the strong electrostatic forces of attraction between oppositely charged ions in the lattice structure.
- Can ionic compounds conduct electricity? Ionic compounds can conduct electricity when molten or dissolved in water because the ions are free to move and carry charge.
