Decreases
Increases
No change
None of these
Electronegativity of an atom is

Noble gases have _____electron affinity.
High
Low
Zero
Very low
Among the following which has the maximum ionisation energy
Alkali elements
Alkaline elements
Halogens
Noble gases
Effective nuclear charge (Z*) can be calculated using the formula
Z* = Z-S
Z* = Z + S
Z* = S – Z
Z = Z* – S
