The first row of elements contains only two elements hydrogen and helium. Hydrogen (Z = 1) has only one electron and it goes to 1s orbital. In helium (Z =2) atom, the second electron can also go into 1s orbital. The electrons mu..

The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to Ne. ..

The last electron enters into 5f-orbital in these elements. The electronic configuration of actinides is given below. The general electronic configuration of these elements is 5f 1 - 1 4 6d 0 - 1 7s 2 . Elementh..
