Considering the atomic number & position in the periodic table, arrange the following elements in the increasing order of metallic character: `Si, Be, Mg, Na, P`.

Explanation

Arranging the elements into different groups and periods in order of their increasing number we have.

We know that the metallic character increases down a group and along a period as we move from left to right . Therefore , Na is the most metallic element followed by Mg and Si, While P is the least metallic element . Among Be and Mg , Mg is more metallic than Be. therefore the overall increasing order to metallic character is `P lt Si lt Be lt Mg lt Na`
