Identify the atomic number corresponding to least number of valence electrons |
| Answer» Solution :The electronic confriguration of element with atomic number 19 is 2, 8 , 8 , 1, number of VALENCE electrons are 1 similarly the electronic configuration of ELEMENTS with atomic number 15 , 35 , and 34 , are 2, 8 , 5 , 2 , 8 , 18 ,7 , 2 , 8 ,18 , 6 respectively and the valence electrons are 5 , 7 and 6 respectively .So the atomic number corresponding to least number of valence electrons is 19. | |
