Use them for better understanding of the subjects. Ion – An atom which becomes charged by losing or gaining electrons is called ion. School Tie-up | Electrons move around the nucleus in circular orbitals. Ionic Bond: An ionic bond is formed at a result of the transference of electrons from one atom to the other. info@entrancei.com Here you can read Chapter 14 of Class 7 Science NCERT Book. When two atoms get bounded by sharing of electrons, the bond formed is called a covalent bond. An electronic component can be an element of an electric circuit that helps in its functioning.
