Atomic Radius
- Atomic Size: defined by how closely an atom lies to a neighboring atom
- Metals- atomic radius is half the distance between adjacent nuclei in a crystal of the element
- Nonmetals- typically form compounds; atomic radius is half the distance between nuclei of two identical atoms that are bonded together
- Ionic Radius
- Atoms gain or lose electrons to form ions
- Electrons gain a negative charge, so a loss or gain results in a net charge
- Ions have either postive or negative energy
- Ions have either postive or negative energy
- Electrons gain a negative charge, so a loss or gain results in a net charge
- Cations: when atoms lose electron they form positive ions and become smaller
- Anions: when atoms gain electrons they form negative ions and become larger
- Atoms gain or lose electrons to form ions
