Question

1) The ionization potential ________ A: goes up and down. B: decreases C: increases. D: remains the same.

2) Atomic size _________ A: decreases. B: increases. C: remains the same. D: sometimes increases or decreases.

3) The electron affinity of the elements in group 1 to 7 ________ A: goes up and down. B: decreases and then increases. C: increases. D: decreases

Answer 1

ionization potential decrease top to bottom in periodic table.

atomic size increases from top to bottom in periodic table.

electron electron affinity decreases top to bottom in a group

Answer 2

1) Ionization potential decreases down the group and increases along the period

2) Atomic size increases down the group and decreases along the period

3) The electron affinity of the elements in group 1 to 7

decreases
