periodic trends
Ionization energy
down the group
decreases
the outermost electrons are father from the nucleus
across the period
increases
The electrons are strongly attrached to the nucleus
atomic radii
across the period
decreases
the attraction force between the nucleus and electrons goes strong making the size smaller
down the group
increases
the addition of another principle of energy level goes electrons increasing the size
electronegativity
across the period
increases
valence electrons are attracted more strongly
down the group
decreases
more protons more nuclear charge and electron shielding effect
