Question

what property do all elements in the same colum of the periodic table as boron have in common​

Answer 1

Answer:

• 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

Answer 2

Answer:

• They have three valence electrons.
• They are electro positive in nature because they have tendency to lose electrons
