In simpler terms, it\u2019s the energy change when an electron is gained by an atom.<\/p>\n\n\n\n<p>For lithium (Li), the electron affinity specifically refers to the process of adding an electron to the positively charged lithium ion (Li\u207a) to form a neutral lithium atom (Li). The equation is:<\/p>\n\n\n\n<p><strong>Li\u207a(g) + e\u207b \u2192 Li(g)<\/strong><\/p>\n\n\n\n<p>Here\u2019s why this is the correct representation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Li(g) + e\u207b \u2192 Li\u207b(g)<\/strong>: This would be the process of adding an electron to a neutral lithium atom to form a negative ion (Li\u207b), which would represent electron attachment, not electron affinity. This process requires energy input, and thus it does not represent electron affinity, which is typically exothermic (releases energy).<\/li>\n\n\n\n<li><strong>Li(g) \u2192 Li\u207a(g) + e\u207b<\/strong>: This represents ionization, where lithium loses an electron to form a cation (Li\u207a). This is the opposite of electron affinity because it involves removing an electron, not adding one.<\/li>\n\n\n\n<li><strong>Li(g) + e\u207b \u2192 Li(g)<\/strong>: This is simply the neutral lithium atom with no change, so it doesn&#8217;t represent electron affinity either.<\/li>\n\n\n\n<li><strong>Li\u207a(g) \u2192 Li(g) + e\u207b<\/strong>: This is the reverse of ionization, where a lithium ion (Li\u207a) would release an electron to form a neutral atom. It\u2019s not related to the concept of electron affinity, which is the addition of an electron, not the removal of one.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, the process <strong>Li\u207a(g) + e\u207b \u2192 Li(g)<\/strong> correctly describes the electron affinity of lithium, as it shows the release of energy when an electron is added to a lithium ion to form a neutral atom.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which reaction below represents the electron affinity of Li?
