In general,the property (magnitudes only) that shows an opposite trend in comparison to other properties across a period is

Which of the following statements are not correct?
$A.$ The electron gain enthalpy of $F$ is more negative than that of $Cl$.
$B.$ Ionization enthalpy decreases in a group of the periodic table.
$C.$ The electronegativity of an atom depends upon the atoms bonded to it.
$D.$ $Al_2O_3$ and $NO$ are examples of amphoteric oxides.
Choose the most appropriate answer from the options given below:

Elements having atomic numbers $33, 47, 53, 59, 68, 74, 82$ are present in which blocks of the periodic table?

The ionisation enthalpies of elements of the second period are given below: Ionisation enthalpy / $kcal \, mol^{-1}$: $520, 899, 801, 1086, 1402, 1314, 1681, 2080$. Match the correct enthalpy with the elements and complete the graph given in Fig. Also,write the symbols of the elements with their atomic numbers.

An element $E$ has an ionisation enthalpy value of $374 \ kJ \ mol^{-1}$. $E$ reacts with elements $A, B, C$ and $D$ with electron gain enthalpy values of $-328, -349, -325$ and $-295 \ kJ \ mol^{-1}$,respectively. The correct order of the products $EA, EB, EC$ and $ED$ in terms of ionic character is $:$

Based on the provided periodic table segment,identify the incorrect statement.
