This means it has 18 electrons. In its Lewis dot structure, Argon has 8 electrons in its valence shell, which are arranged in pairs around the symbol <strong>Ar<\/strong> as follows:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">makefileCopyEdit<code>Ar:  \u2022   \u2022\n       \u2022   \u2022\n       \u2022   \u2022\n<\/code><\/pre>\n\n\n\n<p>Argon is chemically inert because its valence shell is complete with 8 electrons, fulfilling the octet rule.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Lewis Dot Structure for Boron (B):<\/h3>\n\n\n\n<p>Boron (B) has an atomic number of 5, meaning it has 5 electrons. The Lewis dot structure for Boron shows that it has 3 valence electrons:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">cssCopyEdit<code>B: \u2022   \u2022   \u2022\n<\/code><\/pre>\n\n\n\n<p>Boron typically forms covalent bonds by sharing these 3 electrons to complete its octet when bonding with other atoms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Lewis Dot Structure for Sulfide Ion (S\u00b2\u207b):<\/h3>\n\n\n\n<p>Sulfur (S) has an atomic number of 16, so it has 6 valence electrons. The sulfide ion (S\u00b2\u207b) has gained 2 electrons to form a stable 2\u207b charge, making its valence electron count 8. The Lewis dot structure for S\u00b2\u207b looks like:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">makefileCopyEdit<code>S: \u2022   \u2022   \u2022\n       \u2022   \u2022\n       \u2022   \u2022\n<\/code><\/pre>\n\n\n\n<p>The 2 extra electrons fill the valence shell, completing the octet and giving the ion a full, stable configuration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Which of the following compounds is ionic?<\/h3>\n\n\n\n<p><strong>Answer: (e) KF<\/strong><br>Explanation: Potassium (K) is a metal that easily loses its 1 electron to form a K\u207a ion, and Fluorine (F) is a non-metal that gains that electron to form an F\u207b ion. The opposite charges between K\u207a and F\u207b lead to an ionic bond, making KF an ionic compound.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Which pair of elements would be most likely to form an ionic compound?<\/h3>\n\n\n\n<p><strong>Answer: (a) F and Al<\/strong><br>Explanation: Fluorine (F) is a highly electronegative non-metal that readily gains 1 electron to form F\u207b, while Aluminum (Al) is a metal that can lose 3 electrons to form Al\u00b3\u207a. The large difference in electronegativity between these two elements makes them highly likely to form an ionic bond.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Correct Formula for Copper(II) Phosphate:<\/h3>\n\n\n\n<p>Copper(II) refers to copper in the +2 oxidation state (Cu\u00b2\u207a), and phosphate is a polyatomic ion with the formula <strong>PO\u2084\u00b3\u207b<\/strong>. To balance the charges, we need 3 Cu\u00b2\u207a ions for every 2 PO\u2084\u00b3\u207b ions. The correct formula is:<\/p>\n\n\n\n<p><strong>Cu\u2083(PO\u2084)\u2082<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Chemical Formula for Iron(II) Nitrate:<\/h3>\n\n\n\n<p>Iron(II) refers to iron in the +2 oxidation state (Fe\u00b2\u207a), and nitrate is a polyatomic ion with the formula <strong>NO\u2083\u207b<\/strong>. To balance the charges, we need 1 Fe\u00b2\u207a ion for every 2 NO\u2083\u207b ions. The correct formula is:<\/p>\n\n\n\n<p><strong>Fe(NO\u2083)\u2082<\/strong><\/p>\n\n\n\n<p>In summary, the Lewis dot structures represent the valence electrons of elements and ions, while ionic compounds are formed through the transfer of electrons between a metal and a non-metal.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner9-143.jpeg\" alt=\"\" class=\"wp-image-253586\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Write the Lewis dot structure of Argon. 2.
