Answer is (1) - N
<em>Explanation:</em>
I think the given chart is electronegativity chart.
Electronegativity is a
value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is
high, then the attraction to the electrons is high unless the attraction to the
electrons is low. </u>
Electronegativity increases from left to right of the periodic table and decreases from up to down.
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).
The electronegativity values for given atoms are
N - 3.0
Na - 0.9
P - 2.1
Pt - 2.2
