You probably learned in high school chemistry class that core electrons don't participate in chemical bonding.
Give NCERT top priority because practically all exam questions are derived from NCERT examples and text. Concentrate on heavier subjects like thermodynamics, organic chemistry, hydrocarbons, and ...
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...
