Question

what happens to the periodic properties along a period and group . based on
1)IP/JE
2)Electron affinity
3) Electoronegativly
4)Atomic Radius
5)Mettalic character ​

Answer 1

Answer:

Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

Answer 2
