Incorrect statements among the following is/are

A
$2^{nd}$ electron gain enthalpy is always endothermic
B
Electronegativity is the property of bonding atoms
✓
$Al_2O_3$ and $BeO$ are amphoteric oxide
D
None of these are incorrect

✓

Answer

Correct option: C.

$Al_2O_3$ and $BeO$ are amphoteric oxide

c
A is acidic so it belongs to the right side of table and $X$ belongs to the left side of table.

The electronegativities decrease from $X$ to $Y$ to $Z$.

The atomic radius increases in the order $X , Y$ and $Z$ and $X , Y$ and $Z$ could be phosphorus, aluminium and sodium respectively.
