Q. What is the correct order of atomic radius of $A l, N a, B$ and $B e$ ?

$B e < N a < A l < B$

$B < B e < A l < N$

$A l < B e < B < N a$

$N a < A l < B < B e$

So, $B < B e < A l < N a$ is the correct order of atomic radius because along a period atomic radius decreases but the group atomic radius increases.

Q. What is the correct order of atomic radius of Al,Na,B and Be ?

Be<Na<Al<B

B<Be<Al<N

Al<Be<B<Na

Na<Al<B<Be
