Question

Hola ♣♣♣

A transition from metallic to non-mettalic elements is seen on moving from left to right in a period of the periodic table.

Answer 1

Metallic character decreases as youmove across the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down the periodic table.

Answer 2

move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metalliccharacter increases as you move down an element group in the periodic table.
