Question
Arrange the following in increasing order of property indicated
Li, Be, B (ionization energy)
Advertisements
Solution
Li < Be < B
Concept Insight:
Li, Be, B belongs to second period and ionization energy increase as we move left to right in a period due to increased nuclear charge and decrease of atomic size.
