An atom of some element has electronic configuration 2,8,6.(i) What is the atomic number of this element?(ii) Name the element that shows chemical similarity with it. |

Answer» (i) The electronic configuration tells about the number of electrons present in different shells. Thus total electrons can be found by adding the electrons present in all shells i.e. 2+8+6=16. The number of electrons and protons are equal. Therefore, atomic number is 16. (ii) The element with atomic number(Z)=16 is sulphur. The other element which show chemical similarity with sulphur is oxygen. |
