Vedclass · Answer

(A) The basicity of oxides depends on the metallic character of the element. As we move from left to right across a period,the metallic character decreases and the non-metallic character increases,leading to a decrease in the basicity of the oxides.$Na_2O$ is an oxide of an alkali metal (Group $1$),which is strongly basic.$MgO$ is an oxide of an alkaline earth metal (Group $2$),which is basic.$CuO$ is a transition metal oxide,which is amphoteric to weakly basic.$SiO_2$ is a non-metal oxide (Group $14$),which is acidic.Therefore,the correct order of decreasing basicity is $Na_2O > MgO > CuO > SiO_2$.

List-$I$ (Oxide)	List-$II$ (Nature)
$A. Cl_2O_7$	$I. Amphoteric$
$B. Na_2O$	$II. Basic$
$C. Al_2O_3$	$III. Neutral$
$D. N_2O$	$IV. Acidic$

Identify the correct order of basicity for the following oxides: $Na_2O, MgO, CuO, SiO_2$.
