Answer 2

Answer:

$\huge{\mathfrak{\blue{answer}}}$

As we move from Na to Cl in the 3rd period, the size of the atoms of the elements decreases. ... Due to large positive charge on nucleus, the electrons are pulled in more close to the nucleus and thus the size of the atom decreases from Na to Cl.
