2. I are impressed upon the need to take note if the question requires the comparison between nucleus or atoms.
1. I learnt that I need to glance across the entire list of ionisation energy to decide where is the point when the ionisation energy changes drastically.
2. If the atomic radius of two elements from the same period changes due to the change in nuclear charge, why do we still need to explain the fact that the atomic radius changes?
1. A nucleus is positively charged, therefore the beam of nucleus will be attracted towards the negative plate. If an atom is used and it is electrically neutral, does it mean that the beam does not deflect?
