Dear dipanpatel75@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
 
Solution for your first query,
 
  • Atomic size decreases as we move from left to right.
  • This is because, the incoming electron gets added to the same orbital.
  • Hence, the attraction between the positive neutrons from the nucleus and negative electrons in the outermost orbital keeps increasing which results into decrease in size.
 
Regards
