Question

a How does the tendency to lose electrons change as we go down in group 1 of the periodic table Why does it change this way b How does the tendency to gain electrons change as we go down in group 17 of the periodic table Why does it change this way

Accepted Answer

a In group 1 from moving top to bottom the tendency to lose electrons increases due to the addition of shell at each step and atomic radius increases As the size of the atom increases the distance between the nucleus and valence electrons increases b In group 17 from moving top to bottom the tendency to gain electrons decreases due to the addition of shell at each step and atomic radius increases As the size of the atom goes on increasing it becomes difficult for the nucleus to attract the incoming electron
