Question

The correct decreasing order for the metallic character is ______.

Options

• Na > Mg > Be > Si > P

• P > Si > Be > Mg > Na

• Si > P > Be > Na > Mg

• Be > Na > Mg > Si > P

Answer 1

The correct decreasing order for the metallic character is Na > Mg > Be > Si > P.

Explanation:

Moving down the periodic table increases the size of the atom and the tendency to remove electrons. As a result, the metallic character increases as the period progresses from left to right.

As a result, the order of decreasing metallic character is Na > Mg > Be > Si > P.
