He performed the experiment in a discharge tube which is a cylindrical hard glass tube about 60 cm in length. ב.ױ� ����D�a1s�:��1~%�L� The increasing order of energy of various orbital is : 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p <  6s < 4f < 5d .. An orbital can contain a maximum number of two electrons and these two electrons must be of opposite spin. Electrons revolve around the nucleus in circular orbits. Limitat ions:- Could not satisfactorily explain the results of scattering experiment carried out by Rutherford.. Rutherford’s Model: Postulates:-Almost all the positive charge and mass of atom is present in its nucleus. But a shift of one electron from lower energy  4s orbital to higher energy 3d orbital will make the distribution of electron symmetrical and hence will impart more stability. Atoms having the same mass number but different atomic numbers, e.g. Atomic Structure Notes Atoms: -Smallest particle of an element that has all the properties of that element. x��Z[o�H~����O#{w0nw�ۖ� �0'{ќ�재��hp 0&�H�㷪ڗ�IF��U��u�����\�d��}�4�\��l�����CQ�������.��-V۬\���s������� {�y����Ə�q��=���q�gJ2�n���@�[�_�v���ˬf�W޷җ��8+}��>^��������w_`�z���WaG�j߁��-�q�Au��ej��_h�O�����n�bo揔�;����2?\�]�� I�ﮥM�(���ӳE�G�EE̤ Atoms of the element with same atomic number but different mass number e.g. Contact Us | <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 594.96 842.04] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Distance between two neighbouring troughs or crests.
