Archimedes’ Principle
When an object is partially or completely immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the object. 🌊⚖️

🔹 Buoyant Force = Weight of Displaced Fluid
🔹 Explains floating and sinking
🔹 Important for Physics, CBSE, NEET & Competitive Exams

Halogens | Chemistry Study Notes

Halogens are the elements of Group 17 of the periodic table. They are highly reactive non-metals with 7 valence electrons. ⚛️📚

🔹 Elements: F, Cl, Br, I, At, Ts
🔹 Valence electrons: 7
🔹 Common oxidation state: −1
🔹 Reactivity generally decreases down the group
🔹 Fluorine is the most electronegative element
🔹 They readily form halide ions (X⁻)

Perfect for NCERT • CBSE • NEET • Chemistry Revision.

🧪 **Ionic Radius**: Ionic radius is the effective size of an **ion** in an ionic crystal. The loss or gain of electrons changes the size of an atom. **Cations are smaller** than their parent atoms, while **anions are larger** due to increased electron-electron repulsion.

📌 **Key Points:**
• **Cation:** Atom loses electrons → radius **decreases**
• **Anion:** Atom gains electrons → radius **increases**
• Down a group → ionic radius generally **increases ↓**
• Across a period → generally **decreases →** within comparable ions
• In an **isoelectronic series**, higher nuclear charge → **smaller ionic radius**

🔑 **Example:**
**O²⁻ > F⁻ > Na⁺ > Mg²⁺ > Al³⁺**

Alcohols | Chemistry Study Notes

Alcohols are organic compounds containing one or more –OH (hydroxyl) groups attached to a saturated carbon atom. 📚

🔹 General formula: R–OH
🔹 Functional group: –OH
🔹 Classified as primary, secondary & tertiary alcohols
🔹 Important reactions include oxidation, dehydration and esterification
🔹 Examples: Methanol, Ethanol, Propan-1-ol

Perfect for NCERT • CBSE • NEET • Chemistry Revision.

🧪 **Atomic Radius**: Atomic radius is the approximate distance from the **nucleus to the outermost shell of electrons**. It is an important periodic property that depends mainly on **nuclear charge, number of electron shells, and shielding effect**.

📌 **Periodic Trends:**
• Across a period → **Atomic radius decreases →**
• Down a group → **Atomic radius increases ↓**
• Across a period, **effective nuclear charge increases**, pulling electrons closer.
• Down a group, **new electron shells are added**, increasing atomic size.

🔑 **Remember:**
**Across period: Size ↓**
**Down group: Size ↑**

🧬 **Sources of Protein**: Proteins are obtained from both **plant and animal sources**. Plant sources include **pulses, beans, lentils, soybeans, peas, nuts, and seeds**, while animal sources include **milk, eggs, fish, meat, and dairy products**. Proteins provide amino acids required for **growth, tissue repair, enzymes, hormones, and immune functions**.

📌 **Key Sources:**
🌱 **Plant:** Soybean, pulses, beans, lentils, nuts & seeds
🥛 **Dairy:** Milk, curd, paneer, cheese
🥚 **Animal:** Eggs, fish & meat
🌾 **Cereals:** Wheat, rice & oats

🔑 **Remember:**
**Protein-rich foods → Amino acids → Growth + Repair + Body Functions**
