Fluorine, atomic number 9<\/strong><\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<p>A cation is a positively charged ion that forms when an atom loses one or more electrons. Atoms with a high tendency to gain electrons or achieve a stable electron configuration (often by gaining electrons) are less likely to become cations. Instead, they are more likely to become anions.<\/p>\n\n\n\n<p>Here&#8217;s why <strong>Fluorine<\/strong> (atomic number 9) is most likely to become a cation among the options provided:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. Oxygen, atomic number 8<\/strong>: Oxygen typically gains electrons to become an anion (O^2-), not a cation.<\/li>\n\n\n\n<li><strong>B. Fluorine, atomic number 19<\/strong>: This is incorrect as it seems to be a typographical error. Fluorine&#8217;s atomic number is 9, not 19. Fluorine is known for gaining electrons to become an anion (F^-), not a cation.<\/li>\n\n\n\n<li><strong>C. Helium, atomic number 2<\/strong>: Helium is a noble gas with a full outer electron shell and does not typically form ions.<\/li>\n\n\n\n<li><strong>D. Fluorine, atomic number 9<\/strong>: Fluorine typically gains an electron to achieve a stable electron configuration, thus becoming an anion (F^-), not a cation. However, if we&#8217;re looking for an atom most likely to become a cation in a general sense (for example, considering that it would need to lose electrons to form a cation), this choice does not fit well. Since fluorine typically forms anions, there might be a misinterpretation in the context.<\/li>\n<\/ul>\n\n\n\n<p>However, none of the listed options are typically known to become cations easily, but in the context of an atom most likely to be discussed for forming ions, <strong>Fluorine<\/strong> (atomic number 9) is the best fit here for understanding common ion formation.<\/p>\n\n\n\n<p><strong>Correct answer:<\/strong> D (with consideration of the context and typical ion formation tendencies).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following atoms is most likely to become a cation?
