Why ionic radius of a postive ion is smaller than that of its neutral atom?
Answers
Answer:
When an atom has its electrons attracted to another atom it becomes a positive ion. The positive ion is smaller than the original atom. ... This means that with fewer electrons but the same number of positive protons, the size of the ionic radius will decrease.

Answer:
Electrons are negatively charged while protons are positively charged and they both exert pulls on each other. Negatively charged ions have higher negative charges within them, thus causing the electrons to spread out and move away from the nucleus much like how like magnets repel. Likewise, Positively charged ions have stronger positive charges within them and pull their electrons closer to them much like how magnets attract. Therefore, when an atom becomes a positive ion is pulls its electrons closer, decreasing is radius moreover, when it becomes a negative ion, it pulls its electrons closer and decreases the radius.
