The electrons in the outermost energy level (n = 2) are called valence electrons, and these are the electrons involved in bonding. Fluorine has 7 valence electrons, as there are 2 electrons in the 2s orbital and 5 electrons in the 2p orbitals.<\/p>\n\n\n\n<p>(b) <strong>Electrons Fluorine Needs to Share to Become Stable:<\/strong><br>Fluorine has 7 valence electrons but needs 8 electrons to achieve a stable, full outer shell (like the noble gases). Since it already has 7 electrons, it needs to share 1 more electron to complete its octet. This is typical for halogens, which usually form one bond by sharing a single electron.<\/p>\n\n\n\n<p>(c) <strong>Sketch of Two Fluorine Atoms Forming a Stable Molecule:<\/strong><\/p>\n\n\n\n<p>In order to form a stable molecule, two fluorine atoms will share one electron each to complete their octets. Here&#8217;s how this looks in a simple diagram:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">rCopyEdit<code>F : F\n<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The single bond between the two fluorine atoms represents the sharing of one electron from each fluorine atom.<\/li>\n\n\n\n<li>Each fluorine atom now has 8 electrons in its valence shell: 7 from its own electrons and 1 from the other fluorine atom.<\/li>\n<\/ul>\n\n\n\n<p>This creates a stable fluorine molecule (F\u2082) where both atoms have full outer electron shells, which is the most stable configuration for them. This type of bond is known as a <strong>single covalent bond<\/strong> because each fluorine atom shares one electron to form the bond.<\/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-banner6-1155.jpeg\" alt=\"\" class=\"wp-image-261487\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many valence electrons are there in a fluorine atom?
