What is the trend of atomic radii and metallic character in group 14 element.
Answers
Atomic radius: Atomic radius decreases in going from left to right across a period. This decrease can be explained in term of the increasing effective nuclear charge in going from left to right. This means that the valence electrons are down closer to the nucleus, decreasing the size of atom. Atomic radius increases down a group, because of the increases in the orbital sizes in successive principal quantum levels.
Metal:
A metal is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity. These metals are located to the left of the heavy zigzag line on the periodic table. Metallic character decreases as we go to the right across a row in the periodic table and increases as we go down a column.
