Structure of an atom
When we study class 9 science, we will come across the chapter Structure of an Atom. It deals with the fundamental constituents of an atom and the charged particles involved in matter.
An atom is a particle consisting of protons and electrons. It contains a central positive charge known as nucleus. There are different ions, which have varying mass numbers. The mass number, also known as the atomic number, is equal to the number of protons and neutrons present in the atom.
An atom has two regions: the nucleus and the outer region. The outer region keeps the electron in orbit around the nucleus. In the outer region, there are negative particles known as valence electrons. They transfer energy through chemical activity.
Generally, the structure of an atom is similar to a Christmas pudding. Electrons are negatively charged particles that move in circular paths around the nucleus.
