Explain the difference between molecule and atom ?

 

⚛️ Atom vs Molecule (Simple Difference)

🔹 Atom

• Atom sab se chhota hissa hota hai kisi element ka
• Ye single particle hota hai
• Is mein proton, neutron, electron hote hain
• Example: H (Hydrogen atom), O (Oxygen atom)

👉 Atom akela bhi exist kar sakta hai (jaise noble gases)

🔹 Molecule

• Molecule 2 ya zyada atoms ka group hota hai
• Atoms chemical bond se juday hote hain
• Ye stable form hota hai substance ka
• Example: H₂O, O₂, CO₂

👉 Molecule hamesha atoms se mil kar banta ha

Feature	Atom	Molecule
Definition	Single particle	Group of atoms
Size	Chhota	Bada (atom se)
Structure	Protons, neutrons, electrons	2+ atoms bonded
Example	H, O	H₂O, O₂

✅ Easy Formula

👉 Atom + Atom = Molecule

🎯 Simple Summary

• Atom = ek unit
• Molecule = atoms ka group
