Account for the following: 'Li' and 'Mg' show similar properties

The removal of electrons from an atom become more difficult when we move from left to right of a period. Do you agree with this? Justify.

How do the metallic character and non metallic character vary while moving from left to right in a period? Arriving at a conclusion by assessing the size of atom?

The first ionisation enthalpies of second period elements generally increase from left to right along the period. Give reason for this general trend.

Name of elements with atomic numbers greater than 100 are given by IUPAC the first inoisation enthalpies of second period element generally increase from lewft to right along the period. Give reason for this general trend.
