Select the correct statement(s).
Options:(select one or more)
Answer:
A, B, C
Solution:
A. Electron affinity (EA) is for isolated gaseous atoms, while electronegativity (EN) describes a bonded atom's electron-attracting power.
B. Electron gain enthalpy is an absolute energy value; electronegativity is a relative scale (e.g., Pauling scale).
C. EA shows irregularities across periods due to electron configurations, but EN generally increases.
D. EA shows irregularities down groups; EN generally decreases due to increasing atomic size.
Therefore, A, B, and C are correct statements.
