Describe the electronic configuration of a given element. Why are we interested in electrons (two primary answers). (With regard to Human Anatomy and Physiology, what is the importance of electrons?) Solution Electronic configuration is the arrangement of electron around the nucleus of an atom. Number of electrons orbiting the nucleus determines the energy level of an atom. This electron makes the bonds like, ionic bond, covalent bond and htdrogen bond. These bonds help in electrostatic interactions between the molecules and helps molecules like haemoglobin, myoglobin to be folded and form a three dimensional structure and function properly. these electrons helps in phosphorylation, hydrolysisetc,..
