Important Questions from General Characteristics of the p-block Elements
Atomic size generally decreases across a period in the p-block. Why?
Show answer
Nuclear charge increases
Across a period, nuclear charge increases while electrons are added to the same shell, increasing effective nuclear pull and decreasing atomic size.
Which element has the smallest atomic size in the second period of p-block?
Show answer
Fluororine
Fluorine has the highest nuclear charge in the second period p-block, pulling electrons closer and having the smallest size.
Ionization enthalpy increases across a period. Which factor is responsible?
Show answer
Decrease in atomic size
Smaller atoms hold electrons more tightly due to increased effective nuclear charge, requiring more energy to remove an electron.
Which of the following has the highest first ionization enthalpy?
Show answer
Nitrogen
Nitrogen has a half-filled p-orbital configuration (2p³), which is stable and requires more energy to remove an electron.
