Some of the medications that can be used to treat severe HG, like methylprednisolone, can cause birth defects. However, severe dehydration and other complications of HG may be of greater concern.

The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Rytuba, James J (2003). "Mercury from mineral deposits and potential environmental impact".

Mercury is a heavy, silvery-white metal that is liquid at room temperature. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. [9] a b c d e f Hammond, C.

The tobacco plant readily absorbs and accumulates heavy metals such as mercury from the surrounding soil into its leaves. These are subsequently inhaled during tobacco smoking. [108] While mercury is a constituent of tobacco smoke, [109] studies have largely failed to discover a significant correlation between smoking and Hg uptake by humans compared to sources such as occupational exposure, fish consumption, and amalgam tooth fillings. [110] It was allegedly used by allied spies to sabotage Luftwaffe planes: a mercury paste was applied to bare aluminium, causing the metal to rapidly corrode; this would cause structural failures.

Unlike its lighter neighbors, cadmium and zinc, mercury usually forms simple stable compounds with metal-metal bonds. Most mercury(I) compounds are diamagnetic and feature the dimeric cation, Hg 2+

Z (عدد البروتونات في نواة الذرة). يبدأ الصف الجديد ( الدورة) عندما يحصل غلاف التكافؤ الجديد على أول إلكترون له. يتم تحديد الأعمدة ( المجموعات) حسب التوزيع الإلكتروني للذرة؛ العناصر التي لها نفس عدد الإلكترونات في مستوى فرعي معين تقع في نفس الأعمدة (على سبيل المثال الأكسجين والسيلينيوم في نفس العمود لأن كلاهما يحتويان على أربعة إلكترونات في الجزء الخارجي من المستوى الفرعي p). وتندرج العناصر التي لها خصائص كيميائية مماثلة في نفس المجموعة في الجدول الدوري عمومًا، على الرغم من أن العناصر الموجودة في الدورة نفسها، في المستوى الفرعي f، تحظى أيضًا بخصائص متشابهة. وبالتالي، من السهل نسبيًا التنبؤ بالخصائص الكيميائية لعنصر ما إذا عرف المرء خصائص العناصر المحيطة به.

The symptoms of HG typically begin within the first 6 weeks of pregnancy. HG can be extremely debilitating and cause fatigue that lasts for weeks or months. People with HG may not be able to work or perform their normal daily activities.A study in geometric mean urine mercury concentration identified a previously unrecognized source of exposure (skin care products) to inorganic mercury among New York City residents. Population-based biomonitoring also showed that mercury concentration levels are higher in consumers of seafood and fish meals. [75] Skin whitening
