which correctly summarizes the trend in electron affinity?\no it tends to be very high for group 2.\no it tends to be more negative across a period.\no it tends to remain the same across periods.\no it tends to be more negative down a group.

Answer

Answer:

B. It tends to be more negative across a period.

Brief Explanation:

Electron - affinity generally becomes more negative across a period as the effective nuclear charge increases and the added electron is more strongly attracted. Group 2 elements have low electron - affinities due to stable electron configurations. Electron - affinity does not remain the same across periods and generally decreases (becomes less negative) down a group due to increased atomic size and shielding.
