Question

Explain how atomic
radius, valence electrons
and effect nuclear charge
creates the trend for metal
reactivity.

Answer 1

Answer:A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.
