Most atoms are most stable when they have eight valence electrons. This is called the <em>octet rule<\/em>. However, ions form by either gaining or losing electrons to achieve this stable configuration. Let\u2019s evaluate each species:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>1. Rb (Rubidium)<\/strong><br>Rubidium is in Group 1 of the periodic table, meaning it has <strong>1 valence electron<\/strong>.<br>So, <strong>Rb does not have eight valence electrons<\/strong> in its neutral state. However, this question asks for which species <strong>does not have eight valence electrons<\/strong>, and more importantly, others are ions and noble gases, implying a comparison with stable electron configurations. Still, we will consider all of them.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>2. O (Oxygen)<\/strong><br>Oxygen has <strong>6 valence electrons<\/strong> in its neutral state. To achieve an octet, it tends to <strong>gain 2 electrons<\/strong>, becoming O\u00b2\u207b. But the question does not mention O\u00b2\u207b, just O.<br>So <strong>Oxygen (O)<\/strong> in its neutral form <strong>does not have eight valence electrons<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>3. Xe (Xenon)<\/strong><br>Xenon is a <strong>noble gas<\/strong> in Group 18, which naturally has <strong>eight valence electrons<\/strong>.<br>So, <strong>Xe has eight valence electrons<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>4. Sr\u207a (Strontium ion with a +1 charge)<\/strong><br>Strontium is in Group 2 and has 2 valence electrons in its neutral form. When it loses <strong>1 electron<\/strong> (Sr\u207a), it has <strong>1 valence electron<\/strong> left. Therefore, <strong>Sr\u207a does not have eight valence electrons<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>5. Ti\u2074\u207a (Titanium ion with a +4 charge)<\/strong><br>Titanium normally has 4 valence electrons (in Group 4). Ti\u2074\u207a means it has <strong>lost all four of its outer electrons<\/strong>, leaving it with an electron configuration like that of a noble gas (specifically Argon). However, the <strong>actual valence shell is now empty<\/strong>, and it <strong>does not have any valence electrons<\/strong>.<br>Therefore, <strong>Ti\u2074\u207a definitely does not have eight valence electrons<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Final Conclusion:<\/h3>\n\n\n\n<p>While several of these species <strong>do not<\/strong> have eight valence electrons, <strong>Ti\u2074\u207a<\/strong> stands out because it has <strong>zero valence electrons<\/strong>, having lost all its outer-shell electrons. This makes <strong>Ti\u2074\u207a<\/strong> the best answer among the choices given.<\/p>\n\n\n\n<p><strong>Answer: Ti\u2074\u207a<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1338.jpeg\" alt=\"\" class=\"wp-image-41466\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1338.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1338-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1338-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following does not have eight valence electrons?
