Silicon has a more exothermic electron affinity compared to Nitrogen. True or False?<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer: False<\/strong><\/p>\n\n\n\n Nitrogen has a less<\/em> exothermic electron affinity compared to silicon. In fact, nitrogen\u2019s electron affinity is positive<\/em>, which means energy must be supplied<\/em> for it to gain an electron. This is unusual among elements in the periodic table, as most elements release energy when they gain an electron, making their electron affinities negative<\/em> (exothermic).<\/p>\n\n\n\n Electron affinity is the amount of energy released or absorbed when an atom in the gas phase gains an electron to form a negative ion. A more negative (more exothermic) value indicates a greater tendency to accept an electron.<\/p>\n\n\n\n Nitrogen, with its electron configuration of 1s\u00b2 2s\u00b2 2p\u00b3, has a half-filled 2p subshell. This half-filled configuration is relatively stable due to symmetrical distribution and exchange energy. Adding another electron would result in electron-electron repulsion and disrupt this stability. Therefore, adding an electron to nitrogen is energetically unfavorable, making its electron affinity slightly positive or close to zero.<\/p>\n\n\n\n On the other hand, silicon, with an electron configuration of [Ne] 3s\u00b2 3p\u00b2, does not have a half-filled p subshell. When it gains an electron, it becomes more stable by moving closer to a half-filled p orbital (3p\u00b3), which is a more stable configuration than 3p\u00b2. As a result, silicon has a more exothermic electron affinity, meaning it releases energy upon gaining an electron.<\/p>\n\n\n\n In summary, nitrogen resists gaining an electron due to its stable half-filled p orbitals, while silicon readily gains an electron to achieve a more stable arrangement. Therefore, silicon has a more negative (exothermic) electron affinity than nitrogen, and the statement in the question is false<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" Silicon has a more exothermic electron affinity compared to Nitrogen.
