WebThus, each element, at least when electrically neutral, has a characteristic number of electrons equal to its atomic number. An early model of the atom was developed in 1913 by Danish scientist Niels Bohr (1885–1962). In this model, electrons exist within principal shells. An electron normally exists in the lowest energy shell available ... WebAn atom may donate an electron and attain octet configuration or it may gain electron and attain octet configuration. It is also possible that the atom shares its electron (as in O2) and attain stability. The bond formed by donating or gaining electron is called ionic bond. The bond formed by sharing of electrons is called covalent bond
