What is the highest possible oxidation state for elements belonging to the boron family (Group 13)?

A.+1 B.+2 C.+3 D.+4

Why does boron exhibit non-metallic character while other Group 13 elements are mostly metallic?

A.Due to its large atomic radius B.Due to its very small size and high nuclear charge C.Because it has low ionisation enthalpy D.Due to the absence of valence electrons

How does metallic character generally change when descending a group in the p-block?

A.It decreases B.It increases C.It remains constant D.It first increases then decreases

In Group 13, what trend is observed in electronegativity from boron to aluminium?

A.It increases significantly B.It decreases C.It remains unchanged D.It becomes zero

What is responsible for the 'inert pair effect' observed in heavier p-block elements?

A.The reluctance of outer s-electrons to participate in bonding B.The high reactivity of outer p-electrons C.The absence of d-orbitals in the inner shells D.The increase in electronegativity down the group

Which of the following elements in Group 14 is classified as a non-metal?
