What is ionisation energy and why ionisation energy of Nitrogen is greater than hydrogen? |
| Answer» ionisation energy is the amount of energy required for removing electrons from the valence shell of an atom.Now the ionisation energy of hydrogen is higher than nitrogen because hydrogen is very small in size than nitrogen and it has only one electron in it\'s valence shell due to which the attractive force in hydrogen is higher than that of nitrogen due to which hydrogen can\'t loose it\'s electrons easily and take a large amount of energy to loose the electron.<br>Sir can you send me a list of important questions of ncert according to the chapters | |
