CARBON
AND ITS COMPOUNDS
Class 10 • Science • Ultra-Premium Revision Notes
SOURCE RULE
• These notes are organized only from the uploaded lecture transcript.
• The transcript ends during the graphite explanation, so missing continuation is not
invented.
FAST-REVISION DESIGN
One or two focused concepts per page • exam-oriented boxes • diagrams & comparison tables

, 01 • CARBON — BASIC INFORMATION
Key facts
• Carbon is a non-metal.
• Atomic number = 6; atomic mass = 12 u.
• Electronic configuration = 2, 4.
• Outermost shell contains 4 electrons; valency = 4.
• The lecture states that carbon is about 0.02% in the Earth's crust and carbon
in CO₂ is about 0.03%.
WHY CARBON IS IMPORTANT
• Carbon forms millions of compounds because of its versatile nature.
• The lecture connects carbon-based materials with living organisms and materials such as
food, clothes, medicines and fuels.
