Periodic Trends

Question 1

Which periodic trends increase down the group, and decrease across the period?

Answer 1

atomic size

ionic size

electron affinities

bond length

Question 2

Which periodic trends decrease down the group, and increase across the period?

Answer 2

ionization energy

electronegativity

lattice energy

bond strength

Question 3

Atomic size

Answer 3

increases down the group, decreases across the period

as more energy levels are available, size will increase; as nuclear charge increases, decreases across period(charge pulls closer together to make it smaller)

Question 4

Ionic size

Answer 4

radius increases down the group, radius decreases across the period

cations smaller, anions larger

Question 5

Ionization energy

Answer 5

decreases down the group, increases across the period

Question 6

electron affinities

Answer 6

increases down the group, decreases across the period

Question 7

electronegativty

Answer 7

decreases down the group, increases across the period

Question 8

lattice energy

Answer 8

decreases down the group, increases across the period

size of cations and anions smaller across the period from increasing nuclear charge

distance between elements can have a high energy for smaller distances

Question 9

Bond strength

Answer 9

decreases down the group, increases across the period

Question 10

bond length

Answer 10

increases down the group, decreases across the period
