Homework Answers
1)Moving down in a group, the electronegativity decrease due to the longer distance between the nucleus and the valence electron shell
2)no. Of valence electron remain same in the group
3)first ionization energy decrease down the group
4)atomic radius increase down the group Due to the longer distance between the nucleus and the valence electron shell
Hence 1 and 3 is the answer

What are the periodic trends in atomic radius? Select all that are correct. Choose one or more: Atomic radius decreases across a period as effective nuclear charge increases. Atomic radius increases across a period because atomic number increases. Atomic radius increases from top to bottom within a group as the n value of the valence electrons increases.
