Down the group metallic character increases, while in period from left to right metallic character decreases, but non-metallic character increases.
So, the correct order is

N a > M g > B e > S i > P

Alkali metals have more metallic character than other groups.

Q. Arrange the following elements in the decreasing order of metallic characters. $S i, B e, M g, N a$ and $P$ . Select the correct answer.

$N a > B e > M g > P > S i$

$N a > M g > B e > P > S i$

$N a > B e > P > M g > S i$

$N a > M g > B e > S i > P$
