📘 3.3.1 Molecules of Elements – Summary

Molecules of elements are the smallest particles of an element that can exist freely and retain all the properties of that element.

A molecule of an element is made up of atoms of the same type.


🔹 Types of Molecules of Elements:

1. Monoatomic molecules: Contain only one atom.
Examples: He, Ne, Ar (Noble gases)


2. Diatomic molecules: Contain two atoms.
Examples: H₂, O₂, N₂, Cl₂, F₂


3. Polyatomic molecules: Contain more than two atoms.
Examples: O₃ (ozone), P₄ (phosphorus), S₈ (sulfur)


📝 English: Learn about "Molecules of Elements" from Class 9 Science Chapter 3 – Atoms and Molecules. Understand the types of molecules – monoatomic, diatomic, and polyatomic with suitable examples. This topic is important for understanding how elements exist in nature.

📝 हिंदी में: कक्षा 9 विज्ञान अध्याय 3 (परमाणु और अणु) के भाग "तत्त्वों के अणु" को समझें। जानिए कि तत्त्व कैसे स्वतंत्र रूप से अणुओं के रूप में पाए जाते हैं – जैसे एक-परमाणुक, द्वि-परमाणुक और बहु-परमाणुक अणु, उदाहरण सहित।
