Atomic structure and properties from "summary" of NCERT Class 10 Science Solutions by Jagran Josh
Atomic structure and properties are essential to understand the world around us. It helps us investigate how different elements work together to create the things we interact with on daily basis. Learning more about this topic can help us discover new knowledge and advance science.- Atomic structure helps us understand how different elements interact with each other and why they form compounds.
- Every atom has its own unique properties such as electrical conductivity and melting point that are used to differentiate it from another.
- Atoms are the building blocks of all matter, consisting of a combination of subatomic particles and chemical bonds.
- Electrons are known to be the smallest particles in an atom, occupying most of its volume while being held onto the nucleus by electrostatic forces.
- Atoms can ‘bond’ together to create molecules and increase stability through sharing electrons or by forming covalent bonds.
- Stoichiometry is a branch of chemistry that deals with quantitative relationships between particles and atoms.
- Protons determine an element's atomic number while neutrons determine its mass number.
- The nucleus contains protons, which have a positive charge, and neutrons, which have no charge at all.
- Quantum mechanics studies the behaviorof atoms and their motion around the nucleus, allowing scientists to better predict their behavior.
- A force known as van der Waals force comes into play when two atoms come close together but do not form chemical bonds.
