Chemistry ch 10

How are metallic ions formed?

The loss of electronns.
Are metallic ions bigger or smaller than their atoms?

Smaller
How are nonmetallic ions formed?

Gaining electrons
Are nonmetallic ions bigger or smaller than their ions?

Bigger
Atomic radius on the periodic table
- Increase down
- Decrease left to right
Ionization energy

The energy required to remove an electron from its atom
First ionization energy on the periodic table
- Increase up
- Increase left to right
Metals have what kind of ionization energy?

Low
Nonmetals have what kind of ionization energy?

High
Shielding effect
- inner electrons block the attraction of the nucleus (it's far away)
- Lowers ionization energy
4 factors affectiong ionization energy
- 1. Nuclear charge- the larger the nuclear charge, the greater the energy
- 2. Shielding effect-the greater the shielding effect, the less energy
- 3. Radius- the greater the distance between the nucleus and the outer electrons, the less energy required
- 4. Sublevel- electron from a half full or full sublevel takes more energy
Electron affinity

The attraction of an atom for an electron
Metals have what kind of electron affinities?

Low
Nonmetals have what kind of electron affinities?

High
Electron affinities on the periodic table?
- Decrease down
- Increase left to right
