Structure of the Atom Class 9 Notes The central nucleus of an atom, which is surrounded by electrons, is what makes up an atom. Protons and neutrons, which are relatively hefty particles, are found in the nucleus. Therefore, the three primary particles present in an atom are protons, neutrons, and electrons. The atom's nucleus is made up of protons and neutrons. The outermost region of the electron, where it is located, is called the electron shell. Atomic Structure: Different Models Since the discovery of atoms, numerous innovative theories have been created by renowned scientists. Here is a list of the main theories regarding atomic structure. The Thomson Model Apparently, J. J. Thomson, since electrons are entangled in the sphere like currants, the structure of an atom is similar to that of a Christmas pudding. He suggested that A positively charged sphere with contained electrons makes up an atom. An atom is electrically neutral because the protons and electrons in it have simi

What is the Right to Education (RTE)? Following the 86th Amendment to the Constitution in 2002, the right to education was incorporated in Article 21A of the new Constitution. For a long time, it has been necessary to assert that obligatory and compulsory education is a fundamental entitlement for all children aged 6 to 14. This is a critical step toward illiteracy in the country. This addition was worthless because it could not be implemented until the Right to Education Act was passed by Parliament in 2009. The goal of this regulation is to ensure that every child in India between the ages of 6 and 14 years old attends school. He has the right to a good education. Every child has a fundamental right to education between the ages of 6 and 14. This statute establishes basic requirements in primary schools.
