Question

What property do all elements in the same column of the periodic table as boron have in common

Answer 1

The property that all the elements in the same column of the periodic table as boron have is: “the same number of valence electrons (3).  Hence, they all have valency equal to 3.”

Boron is derived from the Arabic word “buraq”.  “It belongs to the 13th group of the p block element”.  Boron is metalloid in nature.   All of them in the group has “3 electrons in the outermost shell”.  

Answer 2

Elements belonging to same column of periodic table means same group.

All elements in same group have same valence electrons, same valency and hence same chemical properties.

Example : Boron - B- Atomic number 5 -- Electronic Configuration -- 1s²2s² 2p¹

Period number -- 2
group number --- 13
Valence electrons --3
Valency -- 3
