Vedclass · Answer

(A) $1$. Comparing the sizes: $Mg$ $(160 	ext{ pm})$ > $Al$ $(143 	ext{ pm})$ > $Mg^{2+}$ $(72 	ext{ pm})$ > $Al^{3+}$ $(54 	ext{ pm})$. Thus, $Mg$ is the largest and $Al^{3+}$ is the smallest. Statement $A$ is incorrect.$2$. The element with atomic number $107$ is Bohrium $(Bh)$, but its systematic $IUPAC$ name is Unnilseptium. Statement $B$ is correct.$3$. $Li$ and $Mg$ show diagonal relationship due to similar charge-to-size ratios. Statement $C$ is correct.$4$. In $[AlCl(H_2O)_5]^{2+}$, $Al$ is in $+3$ oxidation state and forms $6$ coordinate bonds (covalency $6$). Statement $D$ is correct.

Identify the incorrect statement from the following:
