Question

how do the radii of metallic ions compare to the radii of their neutral atoms?

o same size

o larger

o smaller

o variable

Explanation:

Metallic atoms lose electrons to form cations. When electrons are lost, the remaining electrons are more strongly attracted to the nucleus (due to reduced electron - electron repulsion and same nuclear charge). This stronger attraction pulls the electrons closer to the nucleus, reducing the ionic radius.

Answer:

smaller
