define atomic and ionic radius explain with example
Answers
Answer:
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
example Neon, Hydrogen ,Argon, Iron , Calcium .
Ionic radius, rᵢₒₙ, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres
example, while neutral lithium is larger than neutral fluorine, the lithium cation is much smaller than the fluorine anion, due to the lithium cation having a different highest energy shell.
Answer:
- So, See Ionic radius is the radius of an atom's ion in its ionic crystal structure. It is half the distance between two ions that are barely touching each other.
- And Atomic Radius of distance between the nucleus of an ion and the outermost shell of the ion or valency shell.
So Ya these two terms are pretty simple to understand.
I think you can understand.
