RRB Nursing Superintendent | General Science in ONE SHOT | NORCET 10, | RML | KGMU | SGPGI | Part 4 BY Sunny Ma'am Welcome to Part 4 of the Aarogyam Infinity MCQ Series for General Science! 🧪 In this session, Sunny Ma'am covers high-yield MCQs focused on Basic Chemistry (Periodic Table trends) and the Endocrine System, essential for the RRB Staff Nurse Exam 2026 and other competitive nursing exams. This lecture simplifies complex chemistry concepts like Atomic Size, Valency, Metallic Character, and Bonding, while also revisiting crucial biological topics like hormones and glands. A perfect mix for building a strong foundation in General Science! 🔍 Key Topics Covered in this Session: Periodic Table Basics: Groups (18) vs. Periods (7), Alkali Metals (Group 1), Alkaline Earth Metals (Group 2), Halogens (Group 17), and Noble Gases (Group 18). Periodic Trends: Atomic Size: Decreases across a period (left to right) and increases down a group. Metallic Character: Increases down a group and decreases across a period. Element Classification: Metals, Non-metals, Metalloids (Silicon, Boron, etc.), Transition Metals, Lanthanides, and Actinides. Chemical Bonding: Ionic vs. Covalent bonds. Why Carbon forms covalent bonds (sharing electrons). Carbon Properties: Catenation (self-linking property) and Tetravalency. Methane formula (CH4). Endocrine System Recap: Pituitary Gland: Master gland. Pineal Gland: Smallest gland, secretes Melatonin (sleep-wake cycle). Pancreas: Mixed gland (Endocrine - Insulin/Glucagon; Exocrine - Pancreatic juices). Thymus: Site of T-cell maturation. Adrenal Gland: "Fight or Flight" hormone (Adrenaline). Testes: Testosterone secretion. Parathyroid: 4 glands, regulate Calcium levels (PTH vs. Calcitonin). Brain Functions: Hypothalamus (Temperature regulation), Cerebellum (Posture/Balance), Medulla (Involuntary actions). ------------------------------------------------------------------ 📢 PDF Notes Available! 📄 Access on PW App under Aarogyam Reloaded (Free Batch) ✨ Get expert guidance for all Nursing Exams - https://shorturl.at/HbvgR ⭐ Nursing Pro 1.0 (2026) for All Nursing Exams https://physicswallah.onelink.me/ZAZB... ⭐ Nightingale Regular for AIIMS NORCET 10 https://physicswallah.onelink.me/ZAZB... ⭐ Nightingale Regular 2.0 for AIIMS NORCET 10 https://physicswallah.onelink.me/ZAZB... ⭐ Nightingale Fastrack for AIIMS NORCET 10 https://physicswallah.onelink.me/ZAZB... ⭐ Nursing Express 2.0 for RRB Staff Nurse https://physicswallah.onelink.me/ZAZB... ------------------------------------------------------------------------ 📌 RECOMMENDED CHANNELS FOR YOU - 🌐 Physics Wallah - Alakh Pandey:    / @physicswallah   🌐 Competition Wallah:    / @pw-neetwallah   📌 PHYSICS WALLAH SOCIAL MEDIA - 🌐 Nursing Wallah Telegram Channel: https://t.me/pwnursing 🌐 Telegram: https://t.me/Physics_Wallah_Official_... 🌐 Instagram:   / physicswallah   🌐 Facebook:   / physicswallah   🌐 Twitter:   / physics__wallah   🌐 LinkedIn:   / physicswallah   🌐 Quora: https://pwofficial.quora.com ----------------------------------------------------------------- ⏱️ Timestamps: 00:00 - Introduction & New Year Wishes 03:30 - Periodic Table Overview (Groups, Periods, Blocks) 09:22 - MCQ: Modern Periodic Table Basis (Atomic Number) 16:30 - MCQ: Elements in Same Group Have (Same Valency) 18:20 - MCQ: Smallest Atomic Size (Trends across Period) 21:58 - MCQ: Atomic Size Trend (Left to Right) 23:16 - MCQ: Example of Metalloid (Silicon) 25:48 - MCQ: Largest Atomic Radius (Sodium vs. Others) 27:56 - MCQ: Noble Gases Electron Configuration (Octet) 32:55 - MCQ: Most Reactive Non-metal (Fluorine) 34:50 - MCQ: Most Reactive Metal (Potassium) 35:36 - MCQ: Basic Oxide Formation (Metals) 37:25 - Amphoteric Oxides (Aluminum & Zinc) 39:29 - MCQ: Metallic Character Trend (Down the Group) 42:58 - MCQ: Electronic Configuration 2,8,2 (Magnesium) 44:11 - MCQ: Valence Electrons in Carbon (4) 46:21 - MCQ: Why Carbon Forms Covalent Bonds (Sharing) 49:47 - MCQ: Carbon's Property of Long Chains (Catenation) 50:41 - MCQ: Formula of Methane (CH4) 51:46 - Homework Question: General Formula of Alkanes -------------------------------------------------------- 📌 For any Queries or Complaints visit: https://www.facebook.com/nursingwalla...
