Hey...
(a) Boron
(b) Thallium
(c) 3
(d) B2Cl3
(e) less metallic bcz it will become electronegative as we move down the group.
Hope this would help you.
Mark it as brainliest if you like.
@ Saadya

tony19: a) will e thallium because as we go down the group the metallic character increases because the tendency to lose electrons increases as size increases.

tony19: b) will be boron as it is the first member of the the group hence it have higher ionization enthalpy so comparatively it will be more electronegative then the rest of the members of the group.

tony19: d) It will be BCl3
Boron has 3 valence electrons
Cl has 1 valence electrons
So their compound will be
BCl3

tony19: e) the reason is wrong
As we move down the electronegativity decreases

The correct reason is that in a period when we move left to right the metallic character decreases and non metallic character increases .

tony19: Pls if you are not sure dont give wrong answers and wrong reasons just for the sake of getting points.
