the decrease in electropositivity is due to poor shielding effect of s and d orbitals

Why does electropositivity first increase from boron to aluminium and then decrease down the group?
Boron is a metalloid, while aluminium is a metal. The size of the aluminium atom is much greater than boron, so electropositivity increases from boron to aluminium. But then electropositivity decreases from aluminium to thallium due to the poor shielding effect of the d10 orbital.
What are the elements in third group of periodic table?
Boron, aluminium, gallium ,indium ,thallium
Which element in group 13 is a non metal?
Group 13 contain aluminium, gallium, indium, thallium, ununtrium (metals) and boron (nonmetal).
What materialis similar to aluminium?
Boron, Aluminum, Gallium, Indium, Thallium and Ununtrium all inhabit Group 13 on the chart, so they are quite similar to each other chemically.
Whats the atomic mass of thallium 203 and thallium 205?
