Vedclass · Answer

(C) Metallic character is defined as the tendency of an element to lose electrons. Metallic character increases as we move down a group and decreases as we move from left to right across a period. The positions of the given elements in the periodic table are: $P$ (Group $15$, Period $3$) $Si$ (Group $14$, Period $3$) $Mg$ (Group $2$, Period $3$) $Na$ (Group $1$, Period $3$) $Be$ (Group $2$, Period $2$) Comparing these, $P$ is the least metallic (non-metal), followed by $Si$ (metalloid). Among the metals, $Be$ is less metallic than $Mg$ (since $Be$ is in Period $2$ and $Mg$ is in Period $3$ of the same group). $Na$ is the most metallic as it is in Group $1$. Thus, the correct order of increasing metallic character is: $P < Si < Be < Mg < Na$.

The correct order of increasing metallic character of $Na$, $Be$, $P$, $Mg$ and $Si$ is:
