Description : The atomic number of hydrogen is 1. This implies that it contains _______ in its Kshell. (1) One neutron (2) One proton (3) One electron (4) None of the above
Last Answer : (3) One electron Explanation: This implies that Hydrogen has one electron in its K shell. Also, it requires one more electron to fill the K shell. So two hydrogen atoms share their electrons to form a molecule of hydrogen, H2.
