Complete the sentences to identify the trend in first ionization energies as one proceeds down the group 7a elements and explain how this trend relates to the variation in atomic radii.
complete the following sentences using this word bank:
increase
decrease
greater
smaller
1. moving from f to i in group 7a, first ionization energies
2.moving from f to i in group 7a, atomic radii
3. the relationship between atomic radii and first ionization energy going down a column is best explained by the fact that the greater the atomic radius, the the electrostatic attraction of an outer electron for the nucleus and the the ionization energy of the element.
part b. complete the sentences to identify the trend in first ionization energies as one moves across the fourth period from k to kr and explain how this trend compares with the trend in atomic radii.
complete the sentences using this word bank:
increase
decrease
less
more
1. moving from k to kr across a row, first ionization energies slightly.
2. moving from k to kr across a row, atomic radii
3. the relationship between atomic radii and first ionization energy going across a row is best explained by the fact that as atom size decreases it takes energy to completely remove an electron from the atom.

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
