Question

what is The correct order of atomic radii
a. Na>Cl>P>Mg

b. Na>Mg>P>Cl

c. Cl>Mg>P>Na

d. P>Na>Cl>Mg​

Answer 1

$\large\sf\underline\red{Answer \: :-}$

First we find the radii of all given elements.

$\sf\bigstar \: {Na = 0.190nm}$

$\sf\bigstar \: {Cl = 0.154 \: \: or \: \: 0.160nm}$

$\sf\bigstar{ \: P =0.235nm }$

$\sf\bigstar{ \: Mg = 0.16nm}$

According to the radii

$\sf\red{d. \: \: P > Na > Cl > Mg}$
