Question

By considering their position in the Periodic Table, which one of the following elements would you expect to have maximum metallic characteristic?

$Ga$

$Ge$

$As$

$Se$

$Be$

Answer 1

1) Among the elements listed $Be$ and $Ga$ are expected to be most metallic.
2) Out of $Be$ and $Ga$, $Ga$ is bigger in size and hence has greater tendency to lose electrons than $Be$.
3) Therefore, $Ga$ is more metallic than $Be$.
