- Chemistry
- period = down groups = across
- Period 1 = fills 1s orbital
- Atomic radius
- decreases across period (left to right)
- As you go down the group atomic radii increases
- Electro- negativity
- Measure of tendency of an atom to attract a bonding pair of electrons
- increases as you go across a period
- Decreases as you go down a group
- Depends on
- Number of protons in nucleus
- distance from the nucleus of the bonding pair of electrons
- How much shielding there is from inner electrons
- Takes more energy to remove an electron as you go across the period
- period = down groups = across
