Chemical Bonding
Chemistry · रासायनिक बंधन · 12 facts
1
Chemical bond: force holding atoms together in compound
2
Atoms bond for stable noble gas configuration (octet/duplet rule)
3
Ionic bond: electron transfer metal to non-metal; NaCl
4
Ionic: high melting, conduct in molten/dissolved, crystalline
5
Covalent bond: electron sharing between non-metals; H2,O2,H2O
6
Single(1 pair), Double(2: O=O), Triple(3: N triple N)
7
Covalent: low melting, poor conductors, often gases/liquids
8
Metallic bond: sea of free electrons; conductivity+malleability
9
Hydrogen bond: weak H-F/O/N attraction; water has H-bonds
10
Water properties from H-bonding: high BP, surface tension, ice floats
11
Coordinate bond: both electrons from one atom; NH4+, O3
12
Diamond: each C bonded to 4 others; hardest natural substance
