Question

The increasing order of the atomic radius of Si, S, Na, Mg, Al is (A) S < Si < AI < Mg < Na (B) Na < AI < Mg < S < Si (C) Na < Mg < Si < AI < S (D) Na < Mg < AI < Si < S

As we move from left to right in a period, effective nuclear charge increases. Due to this atomic radius decreases. Thus, correct order of atomic radii of

3^{rd}

period elements is

N a > M g > A l > S i > S

Q. The increasing order of the atomic radius of Si,S,Na,Mg,Al is

S < Si < AI < Mg < Na

Na < AI < Mg < S < Si

Na < Mg < Si < AI < S

Na < Mg < AI < Si < S

As we move from left to right in a period, effective nuclear charge increases. Due to this atomic radius decreases. Thus, correct order of atomic radii of 3rd period elements is Na>Mg>Al>Si>S

Q. The increasing order of the atomic radius of $S i, S, N a, M g, A l$ is

As we move from left to right in a period, effective nuclear charge increases. Due to this atomic radius decreases. Thus, correct order of atomic radii of $3^{rd}$ period elements is

$N a > M g > A l > S i > S$
