Be

C

Mg

D

Al

Text Solution

Verified by Experts

The correct Answer is:
A
s -block element are generally metal. Only Be show amphoteric property. In 13 group metallic character increases on moving down the group due to inert pair effect.
Hence boron shows non metallic character.

Metallic Character The ability of an atom to donate electrons and form positive ion (cation) is known as electropositivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size. Non-Metallic Character The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion.Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electronegativity increases due to decrease in atomic size Hydrogen is placed along with Alkali metals in the modern periodic table though it shows non-metallic character
