Recall now that the electrons of elements with increasing atomic number (the number of protons in the nucleus and, therefore, the number of orbital electrons in a normal, un-ionized, atom) occupy the states with lowest energy. The lower energy states are, in general, the quantum states with...
Complete the table to show the number of subatomic particles present in the nuclei of these two isotopes of hydrogen.(1)Isotope Number of protons Number of neutrons}H H(ii) Use the dat a in the table to explain the term isotopes.(2)(b)The relative atomic mass of hydrogen in the ...
Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carries a positive charge and has more protons than electrons. An anion carries a negative...
