Which among the following has the highest ionization potential?
F
C
Br
Ne
Across the period, electron affinity
decreases
increases
decrease and then increases
increase and then decreases
Ionization energy is
directly proportional to size of atom
directly proportional to nuclear charge
increase with less stable electronic configuration
none of these
The bond distance of H-H bond is
1.44 Å
1.98 Å
0.74 Å
2.28 Å
Effective nuclear charge (Z*) can be calculated by using the formula
Z* = Z – S
Z* = Z + S
Z* = S – Z
Z = Z* – S
The electron affinity of an atom
is directly proportional to its size
is inversely proportional to its size
is independent of its size
Electron affinity is expressed in
kJ
J
kJ mol
kJ mol-1
When XA>>XB, A–B bond is
Covalent
non-polar covalent
Ionic
metallic
Pick the correct statement
Carbon having more nuclear charge than boron
The size of carbon atoms is larger than boron
Carbon forms electron deficient compounds
Carbon forms ionic compounds
