Professor Dave Flashcards
Atomic radius ( how big the atom is ) increases along the periodic table ( Up / Down ) and (Right / Left)
Down / Left
- Adding electrons does what to the Ionic Radius.
2. Atomic radius does what when the atomic number increases.
- Increases
2. Decreases
The (further / closer) an electron is from the nucleus the easier to remove
Further
Energy required to remove an electron from an atom
Ionization energy.
The amount of energy liberated when an electron is added to a neutral atom to form a negatively charged ion
Electron affinity
the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule
Ionization energy
Compounds and elements are “Pure Substances”

- All non-zeros are significant
- Zeros between non-zeros are significant
- Leading Zeros are not significant
- ….
- Trailing zeros are only significant when they come after a Decmil point.
