It is general, because the pattern is irregular.
The question is too general; iron for example has a Pauling electronegativity of 1,83.
In general, they are opposing. Electronegativity increases going left to right in a period and up in a group. Atomic radius decreases going left to right in a period and up in a group.
This compound is not ionic compound because the absolute difference in electronegativity between its both elements is less than 1.8. in ionic compounds the electronegativity difference should be more than 1.8 on pauling scale.
The Pauling electronegativity and the first ionization energy increase from sodium to chlorine.
Electronegativity
The pattern is a general trend that is very consistant
going down a group, electronegativity decreases going across a period, electronegativity increases

the difference between the electronegativity values of sodium and bromine is 1.9 , which is relatively high in general , high differences suggest ionic bonds.
Electronegativity decrease going down in a group and increase from left to right; but this isn't a general rule.A similar situation is also with the ionization energy.
The Pauling electronegativity and the first ionization energy increase from sodium to chlorine.
