When moving up and down in the periodic table of the elements, the metal properties change. As you observe from left to right in the periodic table, the metal characters will decrease. This happens because atoms are more likely to accept electrons to fill the valence shell, rather than losing electrons to remove the unfilled shell.

When you look further down the element group in the periodic table, the metal characters increase. This is because as the radius of the atom increases, the electron becomes more likely to be lost; the distance between the nucleus and the valence electron increases, thereby reducing the attractive force between the nucleus and the valence electron.
