Afinitas Elektron Dalam Satu Periode: Trends and Explanation

Powered By Sifat Afinitas Elektron Dalam Satu Periode

Electron affinity, the energy change that occurs when an electron is added to a neutral atom to form a negative ion, exhibits a distinct trend across a period in the periodic table. Generally, electron affinity becomes more negative (more energy released) as you move from left to right across a period. This is due to the increasing nuclear charge and decreasing atomic size, making it easier for the atom to attract and accept an electron. Exceptions exist, and understanding these variations requires considering factors like electron configuration and shielding effects.
