Explanation:
Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
It is a measure of the readiness of an atom to gain an electron. This property is very peculiar to non-metals. The higher the value, the greater the tendency to accept electrons.
Across a period electron affinity increases due to the increasing nuclear charge not being compensated for.
Down a group, electron affinity decreases due to the low nuclear charge and the large atomic radii.
The exception to this rule is the stability of half-filled sublevels. For example, nitrogen has a configuration of 2,5 with sublevel notation of 1s²2s²2p³.
The p-sublevel has a degeneracy of three and the three electrons goes in singly. This makes the configuration stable.
We expect such an atom to have a higher electron affinity but its configuration is stable and carbon would have a higher affinity than it across the same period.
Half filled sublevels are exception to the trend of electron affinity.
Answer:
if the voltage is increased, the current will increase provided the resistance of the circuit does not change.
Explanation:
What type of plate boundary is between the African and south American plate
Divergent plate boundary
DENSITY Gradually increases in moving down from Li to Cs. Because the increase in mass dominates the increase in volume.
<span>But </span><span>Potassium is less dense when compared to Sodium. </span><span>The reason is, the unusual increase in atomic size i. e., atomic volume. This happens because of the addition of empty 3d orbitals. This increases the atomic volume of the atom. Hence we see that anomaly.</span>
