04 periodic properties Flashcards
what is the trend for effective nuclear charges for valence electrons from right to left within each period
increase significantly
what happens to atomic radii down a column
it increases
what happens to atom size across a period
it decreases
what is ionization energy
the minimum energy required to remove an electron from the ground state of that species in a gas phase
what happens to ionization energy from right to left
it increases
what happens to ionization energy down a column
it decreases
what is electron affinity
energy released when an atom in the gas phase accepts an electron
are cations smaller or bigger than their parent neutral atoms
smaller
are anions smaller or bigger than their parent neutral atoms
bigger
what is the trend of ion sizes
ions of the same charge increase in size down the column
