CHEMISTRY

Fluorine is the most electronegative and reactive of all elements. It is a pale yellow, corrosive gas, which reacts with practically all organic and inorganic substances. Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame. It is not uncommon to see fluorine spelled incorrectly as fluorine. ·  [|Symbol] : F ·   [|Atomic number] : 9 ·  [|Atomic weight] : 18.9984032 (5) ·  [|Standard state] : gas at 298 K ·   [|CAS Registry ID] : 7782-41-4 || ·   [|Group in periodic table] : 17 ·  [|Group name] : Halogen · <span style="font-size: 14pt; color: #660066; font-family: 'Century Gothic','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-fareast-language: ES-PE;"> [|Period in periodic table] : 2 <span style="font-size: 10pt; color: #660066; font-family: Symbol; mso-fareast-font-family: Symbol; mso-bidi-font-family: Symbol; mso-ansi-language: EN-US; mso-fareast-language: ES-PE; mso-bidi-font-size: 14.0pt; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msofareastlanguage: ES-PE; msobidifontsize: 14.0pt; msolist: Ignore; msoansilanguage: EN-US;">· <span style="font-size: 14pt; color: #660066; font-family: 'Century Gothic','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-fareast-language: ES-PE;"> [|Block in periodic table]  <span style="font-size: 14pt; color: #660066; font-family: 'Century Gothic','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: ES-PE;">: p-block <span style="font-size: 10pt; color: #660066; font-family: Symbol; mso-fareast-font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-language: ES-PE; mso-bidi-font-size: 14.0pt; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msofareastlanguage: ES-PE; msobidifontsize: 14.0pt; msolist: Ignore;">· <span style="font-size: 14pt; color: #660066; font-family: 'Century Gothic','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-fareast-language: ES-PE;"> [|Colour] : pale yellow <span style="font-size: 10pt; color: #660066; font-family: Symbol; mso-fareast-font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-language: ES-PE; mso-bidi-font-size: 14.0pt; msofareastfontfamily: Symbol; msobidifontfamily: Symbol; msofareastlanguage: ES-PE; msobidifontsize: 14.0pt; msolist: Ignore;">· <span style="font-size: 14pt; color: #660066; font-family: 'Century Gothic','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-fareast-language: ES-PE;"> [|Classification] : Non-metallic ||
