Chemical Bonds
Forces holding atoms together โ ionic, covalent, metallic and hydrogen bonds govern all chemistry
USA ๐ 1916 Chemistry
Key Facts
- 1
Ionic bonds: transfer of electrons between metals and non-metals (e.g. NaCl salt)
- 2
Covalent bonds: shared electrons between non-metals (e.g. HโO water, COโ, DNA)
- 3
Metallic bonds: electron sea model โ explains why metals conduct electricity and are malleable
๐ฌ Did you know? Water's unique properties (high boiling point, ice floats) are due to hydrogen bonds โ weak but critically important for all life
