NCERT

NCERT books for Classes 6 to 10, especially for Science and Social Science, are highly useful to clear the concepts of the topics given in the General Science and General Awareness. 

For AIIMS B.Sc Nursing, its safer to follow the old NCERT. As some exams still ask questions from the deleted portions, please cover the deleted chapters too.

S-Block elements refer to elements in Group 1 and Group 2 of the periodic table namely, the alkali metals and alkaline earth metals. These include elements like lithium, sodium, potassium, calcium, and magnesium. They are called s-block because their outermost electrons occupy the 's' orbital. These elements are highly reactive, especially with water, and are essential in understanding basic chemical behavior. You'll often encounter them early in inorganic chemistry in Class 11. Their simplicity, high reactivity, and biological importance make them fundamental to learning both physical and inorganic chemistry.

Chapter 2 is Structure of Atom, aka the OG Science breakdown of how literally everything exists. You'll learn stuff like Bohr's model, orbitals, quantum numbers — all the nerdy magic that makes atoms behave. Sounds heavy, but once you get the hang of it, it lowkey feels like unlocking the Matrix. Trust the process, and maybe don't sleep through this one.
