The order of ionization energy
s < p < d < f
s > p > d > f
s > d > p > f
s < d < p < f
Noble gases have _____electron affinity.
High
Low
Zero
Very low
Effective nuclear charge (Z*) can be calculated using the formula
Z* = Z-S
Z* = Z + S
Z* = S – Z
Z = Z* – S
Ionization energy is
directly proportional to size of atom
directly proportional to nuclear charge
increase with less stable electronic configuration
none of these
When XA>>XB, A–B bond is
Covalent
Non-polar covalent
Ionic
Metallic
The electron affinity of an atom
is directly proportional to its size
is inversely proportional to its size
is independent of its size
