Chemistry - PERIODIC TABLE Question with Solution | TestHub
In long form of periodic table elements are classified into four blocks s, p, d and f based on their electronic configuration. Periodic properties and other physical properties usually show a regular pattern of change within a group or along period with some irregularities.
On moving from Li to F in the second period, there would be a regular decreases in :
Options:
Answer:
Solution:
On moving from Li to F in the second period, atomic number increases and effective nuclear charge increases.
Due to stronger attraction of electrons towards the nucleus, the atomic radius decreases regularly.
Non-metallic nature and electronegativity increase from Li to F, so they do not decrease.
Ionisation energy also generally increases across the period, so it does not show a regular decrease.
